Cast Iron Briggs and Stratton Carb Rebuild Part 3

[1drivewasher]

Hey Zippo try using a 20lbs sledgehammer when you tap that carb float, it works like a charm !!! And instead of striking up, try downward strokes. Give it a good decent swing, that carb will never give you anymore beef for sure !!!

[ZippoVarga]

@1drivewasher lol...there have been many a time when a large sledge would have eliminated the need to keep tinkering with a stubborn engine. Thanks for stopping by!!

Hi Zippo! I found this video by accident while looking for help with my snowblower carburetor, which is identical to yours. The engine starts easily enough but stalls after a minute or two or when I put a load on it. Seing your video has given me a lot of ideas of what to look for in the carb. I've already removed and cleaned it out but I'm going to take it off again and rebuild it very carefully using this video as reference. Thanks a lot, and you have a new subscriber!

Them old engines had syrup bucket sized pistons and a stroke as long as your arm. U couldn't wearem out even if u tried

Great Videos I just got a new to me Allis Chalmers B-10 1964 or 1965 running rough has a hard time starting and dies shortly thereafter. The carb probally needs adjusted if not rebuilt. Need to completely go over the thing it is a 23 model didn't see a d on tag. just 23 203057  46839 Thanks for the help.

The carb kit came with two main body gaskets. One has an extra hole. The old one came off in pieces. Which one do you use? I have a 190412 Type 2925 Code: 85061109. One gasket has part number 27918 stamped on it, which matches the part number shown in the original manual. The other gasket has no part number but has a hole which alines with a vent in the upper carb body.

[ZippoVarga]

@izogthedestroyer Use the gasket which aligns with the vent hole. There were new and old variations of this carburetor which is why you were given two gaskets with the kit. The older carbs didn't have the vent. Thanks for stopping by my Videos!!

shouldnt you adjust the fuel/idle with the air cleaner on? every time i adjust without an air cleaner, i end up re adjusting anyway when i put the aircleaner on.

[ZippoVarga]

@thegenrl With a new air filter, the setting shouldn't change much if at all. With replacement of the original used filter, you may have to make further adjustments. If you have to make a large adjustment after replacing the air filter, then you might replace the old with new. The foam element filters can be cleaned with soapy water, dried, then re-oiled. The paper elements should just be replaced. Hope this helps with your question. Cheers!

Dear Zippo, I have the exact same engine as yours. It still has a Hale fire pump on it. Anyway, I cleaned it all up, cleaned (didn't rebuild yet) the carburetor and started it up. It sputtered a bit and then started running. Two or three seconds after it got going I hear this high pitched squealing and the engine stops instantly. Thought I snapped the Crankshaft, but right after it stopped the thing turns freely. Checked the shaft key and it doesn't appear to have sheared. Any ideas?

[ZippoVarga]

@mwaugh81 Can't run those pumps dry or they'll seize up when they get hot. Separate the engine from the pump, then try starting the engine again. Don't hook the pump back up until you're ready to put water to it. It's the water that keeps the pump cool and keeps it from locking up. See if that doesn't take care of it. Cheers!!

[ZippoVarga]

@mwaugh81 Also....pull the spark plug and put your finger over the hole and crank it over (keep the coil wire AWAY from the engine and your hand or you'll get a nice shock) If the engine sucks your thumb into the hole then tries to push it out, then then engine is still in one piece. If not, you blew the connecting rod.

Hey zippo, I have an old simplicity 7010 w/11hp briggs. Newer carb, engine was rebuilt about 30-50 hours ago. It spits and sputters under a load, I watched your videos on the govenor and carb adjustment. Copied it to a tee, and still having similar issue. It has to be something small I am missing. Any tips?

[ZippoVarga]

@unclemilty79 Main jet mixture is the culprit. Turn the screw in 1/2 turn and see if the problem stops. Continue adjusting the main jet to get the optimum power from the engine when under load. Idle should be 1100 or there abouts and your idle set screw will keep the low idle smooth. Let me know how you fair. Cheers!!

[frecatoax]

Hey Zippo great video. I have an old 11hp briggs on my little wonder blower and was wonder if you could help me out. Its the 4 screw version and I wanted to know if you had a picture of how the throttle is hooked up, I don't think I am getting any gas to the carb. Thanks.

[ZippoVarga]

Thanks Wolf! Some carbs are easier than others to rebuild. This one had some serious oxidation in the threads of the main jet and it was a real bear to get the old one out.

[mrwiggles2]

Zippo! Nice video, very helpful! What a sweet motor.

[ZippoVarga]

Thanks MrWiggles!

[CSAKvids]

haha. Nice brain fart. I do that allll the time.

NIce how too. Definatly gonna make myself a carb screwdriver.  Take care Sean!

[ZippoVarga]

I stripped out more main jets before making that screwdriver. It really is a jet saver. Thanks Charles!!

[More350Power]

Hey zippo, great vid..... Thumbs UP! That looks like one hell of an engine!

[ZippoVarga]

Hey 350! That 9hp saw very little use over it's life. I just wish it didn't have that damn tapered shaft on it! I may have to change out the crank shaft so I can use it for more than a shelf queen! lol

[edzgarage]

Runs nice!

[ZippoVarga]

Thanks Edz! Not bad for sitting a couple years.

[snoman2]

lol pretty kool ! very helpful info my carb runs good on full blast but on slow idle it back fires i have 2 mess with it a little more

[ZippoVarga]

Thanks!!
