Tractor Question

My guess is carb. Updraft type? I`ve never owned or worked on old tractors, but maintain my old industrial L head engine on a welding machine. Remember the old farts beating on carbs with a hammer? well, their`s a method to the madness. 50 plus years later they still use the same style carb casting, although with a electrical fuel shutoff solinoid, nothings changed. I believe your float is hanging up. It can hang to kill fuel or flood also. This is very tricky to tweek float not to hang on its full swing. You cant see it, you have to assemble and listen carefully, tilting the carb back and forth to hear if float is hanging up. have fun, I did`nt, aprox. 20 r/r to finally figure what was going on.:banghead: Hopefully you`ll benifit from my agonizing effort.
