Ok so, took this carb apart and cleaned it out, put it back on and well, you can see the rest in the pic...yes that is gas leaking...no FLOWING out of the carb. What did I do wrong? Or what is wrong? This is on a 2012 btw. Thanks!

My guess is that either the gasket is catching the flote, or the flote and inlet needle valve are re assembled wrong

I agree, it's the float being held. Only other time I had one leak that bad, I had dropped the needle without realizing it while I was putting the bowl back on. Found it where I left it when I took it back apart :D

Yep what the other guys said, only way to get gas coming out like that is float/needle not in place or stuck open. With it flowing out as fast as it is I would almost put money on the needle fell out of place when assembling it back together.

Yep, appears float or needle is sticking. Another possibility is the emulsion tube isn't seated. That's the long jet tube that runs at the angle & high speed adjustment screw goes into.

There is another issue with this carb that will cause that. The jet that goes up through the bottom and holds the main mixture screw has to be removed when you disassemble the top half. If you don't, the jet can be damaged. The jet has a taper on it that has to seal gas up in the float bowl. If it isn't real tight or ther is a piece of crud holding it, the gas will leak just about as bad as a float problem. To check the float, needle, and seat I hold the carb right side up and blow into the inlet, air should go through. Flip the carb upside down and blow through it and it should hold.

That's the emulsion tube I referred to. Yep, they can leak something awful!

Ok took it back apart and there is no shaft...my buddy (who had cleaned it the first time) just told me he never did get it totally apart. So, don't know where the float shaft went but I need one and have no idea what they are even called let alone what engine this is or anything. If anyone could help me on this, I would appreciate it.

I've made the float shafts from nails before. Just find one that fits, then clip it off & smooth the ends.

Like Dan says, it can be made out of about anything the right diameter. Your working on a Briggs and Stratton engine and the carb is called a Flo-Jet. You need the float pivot pin. If you can't find something to make it out of, take the carb to a Briggs dealer and they should be able to fix you up.

That's the needle valve that the float works. The piece in the carb is called the seat. They are usualy sold as a set. The carb kit for that carb isn't very much and would have everything you need.
