I have a Briggs 21hp 407577 0292 E1 engine that I just put a new carb kit in. It starts easy but after about 2 seconds it starts to smoke (white gas smelling) and runs really rough. It has no HIGH speed on the throttle. When i push throttle up it stays same. Governor seems to be real stiff but when I took the springs off...governor seems to be free and easy. Once in a while I can start it and move governor up and down and it will start to tun at a higher speed but then slows right back down. The engine also pops a lot when running. Seems that if I mess with governor it smooths out and sounds good but doesn't last more than a 1/2 minute then back to bad idle and popping. Any suggestions?

Sounds like when you went through the carb, you lost the high speed jet, which is real easy to do on those junk carbs.
Click on the link I put up, the jet is ref # 117, it is just pressed in, you likely lost it when you cleaned the carb, the o-ring is the only thing that holds it in place, with it missing, you will run, but run rich as hell!!!!
