Interesting Misfiring McCormick 1-1/2M Engine

[mikeD813A]

nope! its throttle governed

[Thesupersmith79]

Good catch, most people would walk by and assume a hit and miss engine! Maybe it had a bad mag or something, but either way goes to show how tough those old one lungers were

[minneapolismolineman]

i think its running a bit rich

or not enuff gas i dnot know mine did the same thing

[minneapolismolineman]

Its throttle governed but just to irritate the bejesus out of the purists i call em one lungers. Its a good ol reliable engine too.

[JasonMann8]

you could make a song outta this

[rreidnauer]

No biggy.  It just wanted to be a hit & miss like all it's buddies. :-)

Farmboy460, I agree with you! I just restored an old M, had a blast with that! No one understands that they are throttle-governed though...

[farmboy460]

@wes4569 Yup i know it people see the spoked flywheels and similar design to the hit and misses and assume that they are all one and the same.

[CokePolarBear1234]

it is

[farmboy460]

Steam knows what he is talking about i love all the people who try to tell a man who know what this is and is around them alot how he is wrong and that it isnt what it is what that is is a THROTTLE GOVERNED McCormick-Deering M

[IronCity2006]

Reason for the weird fire order...........Under load she will hit everytime. Without load on a throttler it will freewheel causing the gov to hold the throttle plate closed. No gas means no fire. All of my throttlers do it, if they didnt they would overspeed. Hit miss engines fire and latchout the pushrod holding the exaust open, but when under load fires everytime and does not latchout.

As for the comments about IHC and McCormick, they are both the same engines, same parts, same numbers.

This engine is a "Hit and Miss Engine"

[steamcheng]

No, actually it is not.

[CokePolarBear1234]

@steamcheng yes, actually it is i got 3

[farmboy460]

@CokePolarBear1234 Well you sure have some poor running M's then they are THROTTLE GOVERNED engines not hit and miss a hit and mis locks the exhaust valve out so it cant fire then then unlocks and the intake sucks gas in it fires and latches the exhaust out again NEVER constant attempts to fire: pushing in exaust everytime and if it was running correctly would fire everytime.

[SthealthRaider]

@elcoyote54 it isnt.... look at the valve.... it isnt stuck like in hit n miss

[JimPrower]

Perhaps someone restored it with the incorrect ignition system.

[pumpkinheadedsob]

The missfire is the govener, McCormick stationary engines with a top carb dont have a throttle butterfly they have a magneto interupter, if the govener was set about 100 rpm slower it'd hit every time.

[steamcheng]

May be the case with some of them, but this one is a Model M, which is indeed a throttle governed engine, and not a hit and miss. It should fire after every compression stroke regardless of load. There is something not quite right here, and may be due to a number of things. However, it is NOT due to the intentional interruption of the ignition as in hit and miss engines.

[WorkFromHome001]

Magneto short!

[Enginemagic]

I have a Fairbanks Morse ZC 118 that runs like that when fuel setting is lean

[fonephat]

A McCormick engine will not fire all the time unless its under load. fone

phat.

[steamcheng]

Well, some of them work that way. However, this one is throttle governed and should fire every cycle whether under load or not! ;)

[angamoos]

at last someone who realises its a throttle governed engine!!!!

[pbgd3]

I've had other throttle governed engines which "miss" when the governor shuts them back. Plenty of throttle governed engines have a governor so they hold rpm under load. You run them with out a load and the mass of the flywheels closes the throttle between every ignition, and some of them also close their ignition.

these things run icecream machines at the NC State fair, bout 3 of them in a row churnin up some ice cream

[318Captain]

Really? I guess there is a reason to there after all.
