The gaskets go on the plastic part first before you put back to geather

[@randalln9215]

Thanks for that video, sir. Ordered a B&S carb kit that has that little o-ring along with the other gaskets, etc. Thought about getting one of those new cheap Chinese aftermarket carbs and just replacing it.....but figured it would be better just rebuilding the original one. Btw....the Briggs kit is about $15 cheaper than the John Deere one....same exact kit too. Keep up the good work!

Thank you

[@earlpowers4157]

Had a s…load of gas blowing out of cylinder when I removed plug. That small o ring was toast so I’m guessing that is why. Think I’ll just throw a new ready to go carburetor on in case there are bits and pieces throughout the carb. Will check the oil to make sure no gas got in it.

Ethanol is the cause of nearly every engine problem I've had.

[@RepairGang]

I feel that my guy but if people use it and don't let it sit 90% of the time the average person will not have a problem.

[@reaperasylum]

And that's why I stopped using ethanol fuels and either run non ethanol fuel which in my town only 1 station runs it and it's the 91+ only or I run canned fuels from Lowe's. I have ran regular but I mix stabilizer in when I do

That is an "o" ring. If you have an assortment than just match it up. Thanks for the fix!

[@Gamer-Family76]

I was wondering if you could tell me what’s wrong with my lawnmower my lawnmower would not start so I was thinking that it had a bad carburetor so I replaced it with a new one and it still will not start if I choke it it will not start but if I put my hand over the air intake to choke it it will start and if I spread my fingers apart to barely get air inside of it it will stay running but if I remove my hand it gets too much air and dies

[@RepairGang]

100% something's gummed up and your carburetor and your fill lines in your fuel pump or you got bad gaskets so I take it apart again. Re-clean it and see if you can fix it again and replace all the o-rings and gaskets. Make sure everything is there from carburetor to intake and so on and so forth

[@thenexthobby]

Or if you use ethanol free gas this isn't an issue, or if you have a different carb that doesn't use that little gasket this isn't an issue, but if your needle/seat or float is bad, any carb will flood.

[@erickv8684]

I want to bypass the electric solenoid under the carburetor and install and static jet screw instead. I'm thinking the soleniod is the problem, because it causes two problems. 1. Lack of fuel. 2 Floods the carburetor because its stuck open. Maybe the solenoid wires can be connected together and the solenoid replaced with a static jet screw?❤

just remove solenoid and clip the needle off thats how you bypass it

So it may be the issue you said, but alone Im not seeing any fuel passing into the spark chamber. Im thinking its the solenoid. It dies out due to a lack of fuel.

My carb was flooding so badly, at times I would see fuel under the mower, and it would no longer start. I'd come back the next day, and it would run again. I tried all the tricks I could find on KZbin. I finally figured out the problem. It was the little rubber tip at the end of the needle valve.

I had the mower looked at twice by our local shop, but they didn't catch this.

My Briggs & Stratton will start and run fine but after I shut it off gas leaks into the engine. Does this fix that problem?

[@billseivers3528]

Probably not. The solenoid under the float bowl usually sticks in the down position which lets the fuel pass through the bowl and into the cylinder, through the valves and into the crankcase. Be sure to check your oil and if it feels really thin, or if it smells like gasoline, then you need to replace the solenoid or install an in-line fuel shutoff to stop the fuel from flowing into the carb after shutting the mower off.
