Bought an 87 foreman and have been working on doing a little restoration on it. A little background: Guy I bought it from had it converted into a gravity fed system because the fuel pump went out and he didn't want to buy a new one. Ran perfectly fine but still wanted to convert it back to normal. Found an OEM fuel pump, replaced the tank because the original one was rusted through, new fuel filter, and ended up having to replace the fuel cut relay as well. I cranked it up for the first time after and gas was pouring out of the overflow of the carb. Pulled the carb, cleaned it real good, used a rebuild kit to replace jets, gaskets, and float valve. Cleaned the float too which looked to be in pretty good shape. Put the carb back on, cranked it up and gas was still pouring out of the overflow. A buddy came by and we pulled it out again and found a tiny piece of rubber that somehow was missed during the clean that was stuck in the float valve. We figured that was the problem so we put it back on, cranked it up and no leaks. Ran great for over a week but went to crank it tonight and same problem, gas started pouring from the carb overflow again. After running for a little bit it eventually shut off. Wanted to see if anyone had any advice of anything I may be overlooking before I pull it out again. Feels like I might not have ever fixed the problem. Any suggestions would be appreciated! Thanks for the help!
1987 Foreman Carb Issues

Hello and welcome to the forums!
Great job so far...! Congrats on getting an old Foreman! Got any pics to share...?
Your issue can probably be solved by putting the original OEM float valve back in the carb.
Aftermarket carb kits generally contain cheap chinese parts that are no more useful than a stinkin' bag of garbage. Take all of the parts out of the carb that were in the kit, except for the rubber o-rings and the rubber bowl ring/gasket. Put the original jets and other hard brass parts back in it... set it up exactly as the service manual recommends, then come back and share the results with us.

.Thanks @retro and @shadetree !! Followed y'alls advice and put back all OEM jets and float valve, cleaned float valve seat and also removed the drain screw and cleaned that part of the carb real good. That was one thing I missed in the clean and looked like there was a good bit of grime in there which could've caused the screw not to seal properly. No leaks after putting it back on a cranking it up. So far so good! I'll let y'all know if I have any other problems and will share some more pics as it comes along. Thanks again!
