  • is there a way to install this motor on my scooter?

  • At the RPMs shown in this video is it possible to stop this engine by a man's hand? Not a very normal question, but still a question! XD XD I just don't have any sensibility to understand how much power a human hand can make to stop an engine (in general terms, of course)... In this particular case I'm asking because the engine is working with low rpm so... could it be possible?

  • how did you make this? i have an old air compressor too but how do i convert it

  • this would be great for my 18ft sailboat, but throttle it up for travel and let it hit n' miss for idle

  • This does not have a large enough flywheel.

    A hit and miss engine should keep something of constant speed.

    But there is the other half of the answer, an air compressor uses the driving motor or engine as the primary flywheel.

    Another flywheel would smooth things out.

  • whats powering it.

  • Ok, i understand everything except the lack of a camshaft turning half as fast as the crank, i do not see one! lol

  • amazing vid you made

  • wonderful creation

  • woow supercool

  • Sounds like a roflcopter. Nice work, you should make a set of plans.

  • Nice work. What are you going to power with this?

  • hi what did you use to make this engine thanks

  • wow! cool! thanks for posting!

  • You should use it to run an identical model Curtiss compressor and make yourself a functioning air compressor. Would be kinda funny.

  • how you made gas intake? :P

  • I looked on ebay to find an old compressor because id like to do somthing like this. I could not find much on there where do you get yours?...ebay...lol....I found one at a thrift shop, they put my name on it so that they could have someone price it, and then someone stole it...how nice. It would have been perfect, that was about 6 months ago, im still holding a grudge to it, its just one of those stupid things that doesn't matter that much but really bothers you. oh well

  • oh that is just too cool it is using centripical force when it slows down i think so it can shove a blast of air too push it faster.

  • Great job. 

  • Cool! I'd love to see the governor mechanism when engine is off.

  • Fuck the oil Company put one of those on a scooter that rolls a fat 300lbs dude around at 25mph and your a Billionaire!!!!

  • Any idea what the HP of this is? Sorry if this is posted somewhere in previous comments. Very nice work!

  • damn, great job!! so the cilinder is from an air compressor? and where does it run on?

  • Hell Yes!!

  • put put put Put Put Put PUTPUTPUTPUTPUTPUTPUTPUTPUT...­....... put

  • @Bamchucknorris PUPUTTPUTT shshshshshshshshshPUPUTTPUTT shshshshshshshshshhshshsh PUPUTTPUTT shshshshshshshshshshshsh PUPUTPUTPUTPUTPUTPUTPUTPUTPUT shshshshshshsh PUPUTTPUTT!!

  • Love the engine man!!! ?These engines are scarce as hens teeth. and you either need to know a good machinest or be one, to keep them going... Great to see an alternate that uses modern stuff!!! To the youngsters who make negative comments... A people who don't know where they come from have no future.... Some of you have no future... You people are sad indeed. Go back to your nintendo, which will be obsolete in a month, like you will be. buh-bye

  • Sir,you are a genius! Well done!

  • what did you do take apart a old air compressor?

  • What fuel does it use?

  • @wilzchau Probably anything compressed (:

  • my hat comes off to you Sir... your hit & miss is a work of art, i'm thoroughly impressed and amazed........... i feel sorry for all the kids out there that don't know what a hit and miss is and then leave negative comments on your video expecting to see a DOHC 4 valve per cylinder super charged nitro burning V-8 hemi

  • Do you have plans for converting a compressor into an engine? There are good things about this type of project: 1 recycle, 2 reuse, 3 most of the hard work is done as there seems to be no major machining involved. Well done!

  • How long did this take? Would you say it runs as reliable as any other engine? Is it a durrable as other engines? I'm just wondering, but imo great job.

  • i like the governor you put on the flywheel pretty cool

  • This is awesome! Wish I'd thought of it!

  • This made me laugh! Great stuff!

  • you can help me av*navig8, what is a hit and miss motor?

  • A hit and miss engine fires only when needed to maintain a speed. The intake valve is what is called a "poppet" valve, in that it's opened by the vacuum of the piston moving toward the bottom. The exhaust valve is forced open by spinning weights to prevent compression from slowing the engine. When the exhaust closes, the vacuum is created to open the intake, and therefore, fire the engine. Pretty awesome design for ~1910 I'd say.

  • @shinyedgestudios

    Hit and miss engines use less fuel when idling, so why aren't they built anymore? In fact people consume alot more gas just by letting their car engine idle when their stopped in the middle of the city transit.

  • hey where did u get the plans

  • i would say he never had any... most contraptions like this come from a man's (or women's) ingenuity..

  • Nice machine. How do these hit&miss engines work?

  • i was thinking the same thing, what is a hit and miss engine?

  • i think they have a Governor of some kind that mechanically measures the speed of the engine (like the traditional swing ball governors on a steam engine). when the engine gets below a certain speed it engages the ignition and valve system and it fires the engine again, which increases the speed of the engine and stops it stalling... its primarily to save fuel i would guess....

  • Nice work! How the heck did you get it to go? Ive been wanting to do this.

  • just to let you know a hit and miss engine does leave the exhaust valve open to "Freewheel" until another power stroke is needed then the exhaust valve will close causing a full 4-stroke cycle. unless you were talking of a different motor when u said Hit & Missed?

  • is that a 4-sroke?

  • hahaha, that sounds hilareouse!

  • how you made your carberatur?

  • And where is the air intake?

  • is it a throttle governed one??

  • Comment removed

  • uerka it works lol great job man like your style one of the true pioneers ha

  • does any one know where i could get plans to build a hit and miss engine from???

  • very nice

  • It would be neat to use it to drive a compressor of the same model, pumping air.

  • so its governed?,, great job

  • How u make these?

  • if you were to put a hit miss engine on like a go-kart wouldn't it run like a regular engine since its not freewheeling

  • no, hit/miss engines dont have carburetors so they have a governor that will hold the exhaust valve open until it goes down to a certain speed and then it will close and fire again, its not like todays small engines that you can speed up and slow down at will, these are meant to run stationary usually at one speed.

  • ya if it was on equipment then it would fire all the time right unless it gets up to speed.

  • that all depends on what its on, if its on something that it doesnt have enough power for then it will be firing all the time trying to keep up, but usually it will still have a few miss cycles in there

  • @motox458 

    Some have carburetors..

  • @SthealthRaider

    hit and miss never had carburetors, they were called hit and miss because they had no other way of controlling engine speed other than to hold the exhaust valve open thus causing a "miss". there are large flywheel engines that are throttle governed with a carburetor, but they're not considered hit and miss because they have a controlled flow of gas so they don't need to "miss" every few strokes in order to not speed out of control.

  • Thats very wrong, carburators dont control engine speed anyway. Governers do. Of course hit and miss engines have carburators

  • governors don't control the speed of the engine, they control either the exhaust valve on a hit and miss engine and on a carbureted engine they control the throttle, but hit and miss engines are not throttle governed, they are governed by the exhaust valve staying open thus creating the "miss" to keep it at a proper speed, the later flywheel engines had carburetors and they would generally hit every time, the throttle would maintain the speed

  • actually some just draw the fuel vapors off the top of the tank

  • also adding to my last comment, a hit and miss engine uses what is called a check valve which is basically a needle valve that allows fuel into the engine, they also have what is called a mixer which is a small air valve regulating the air flow that goes into the engine to keep it from running rich or lean. this is different from a carburetor because they didn't have any way to really regulate the fuel control enough to eliminate the need for the "miss" at at period in time

  • @motox458 OK dude your still wrong. carburetors dont control speed, the throttle butterfly or slide usualy built into a carb does. A carb is a device that mixes air and fuel to the correct ratio for combustion not a device for controlling speed, if you take a throttle butterfly controled carb and remove the throttle butterfly and plug the throttle jet in the carb the engine will sit and run at idle although a very high idle and at a lean conditon but a constant speed none the less.

  • i never said carburetors controlled the speed, i said the speed is controlled either by holding the exhaust valve open creating the miss, or by a carburetor with a throttle, hit and miss engines have what is called a check valve to control the air/gas ratio which is a very simplified version of a carburetor, but its still not a carburetor and the speed is controlled by a governor holding the exhaust valve open

  • you must have a loose grasp on the english language because you said "throttle governed by the carburetor" this statment implies that your definition of carburetor means only carburetors with built in throttle. and it dosnt matter how simple a carb is its still a carb. I know the english language is difficult to understand when you only have a second grade education.

  • heh, thats a good one coming from a pumpkinheadedsob

  • try reading more carefully, i said throttle governed, with a carburetor, implying that a throttle governed engine has a carburetor

    and for god sakes, if you would read a bit you would know the difference between a hit and miss engine and a throttle governed flywheel engine

  • go check your punctuation jackass. because in your orignal statment of "throttle governed with a carburetor" by and with are interchangable with that punctuation being used. If you change the punctuation "throttle governed, with a carburetor" with and by are no longer interchangable. Stop trying to backpedal and learn to master the english language.

  • my. punctuation? is, not/ the^point! of (this* conversation)

    my point is there is a difference between a hit and miss engine and a throttle governed flywheel engine

  • could you show me how you did it

  • i think it's NEAT!

  • what modern improvments can be made? Spark plug?

  • It's got one already!

  • Hi,

    Is this water or air cooled?

    Great job!

  • Air cooled, same as when it was an air compressor. The flywheel has fan shaped spokes.

  • Thanks. I supose when it only fires every 20 cycles or so it doesn't get that hot.

    Cheers.

  • Great job!!! How have you built it? Low rpm engine are more reliable. I have interest for plans

  • awesome,

    Do you sale plans on how to do this? I would be interested. Have a great day.

  • I love these hit and miss engines!

  • When he put his hand in to speed up the engine, it sounds a little bit like the uzi / automatic pistol in GTA San Andreas.

  • I have had cars that did not run this good.

  • was it hard to make it ??

    please reply

  • excellent job, unique ..

  • Nice

  • Whats the hose for?

  • thats his exaust

  • That's great that you could make this; nice job!

  • lmao

  • Electronic fuel injection serves the same purpose, only it's much smoother.

  • Hit & Miss engines were used as power plants on farms prior to and up to the mid 1940's before power lines were available in remote areas. They were steady running and reliable for the time. You could put a leather belt on the flywheel and run a water pump, a Saw, generaator,or even a washing machine!

  • nice system!

  • It have cluth??

  • looks like an old air/fridge compressor?

  • You're joking right? getting them to run slow (with no load) is key to the economy of this design. No fuel is used during the 'miss' phase. (Exhaust valve open, no compression, no suction, no fuel!) it only draws fuel, and fires, when needed. Old tech., and it will make a comeback!

  • Comment removed

  • baaaaaaa

  • @av8navig8 Let's hope so... We need something to save us! I would drive a model A anywhere 35 mph... :)

  • @av8navig8, i had to remove that comment, i dont want people looking at me as a moron, i understand how they work now, i actually figured that out not long after i posted the comment, i feel like such a moron putting that on there.

  • they are verry reliable engines verry good design

  • Putt Putt!!

  • Nice! I've seen a similar mod job at the Cumberlan Valley Antique Engine Assn's Steam & Gas show, however the guy who made the engine machined a new, longer crankshaft, so his engine would have 2 flywheels, as would be more typical for a Hit 'n' Miss engine....

    I'd like to get my own Hit 'n' Miss, but I may settle for buying a kit to build a 1/4 scale model of one of the reid engines instead.

  • It is possible to make engine from big bore, low stroke compressor (opposite of this)? There are no curtis-like compressors in Czech republic :-(

  • I would refer you to "Flywheelfarm" (on youtube) He is the genius behind this engine. Search the name, he has many engine vids, and my bet is, he would be happy to help.

  • what kind of fuel supply does the engine run on?

  • Hi Jack, (couldnt resist) the fuel is regular gas, the tank is in a hollow spot under the the crankcase. (copper tube from tank to mixer), crankcase oil is above that. Runs all day on a quart of gas! Credit goes to "flywheelfarm" (youtube) for making this one.

  • GREAT!!  If you want to see a vid on a small engine go to my channel(i only have one vid)

    its on a ski with a rudder an everything! I'm making a modification by trying a different ski from a GT sno-racer!

  • reminds me of my old lawnmower engine. the flywheel based governener was screwed up, and did that.
