I've had to re-tighten the screws a couple times because the carburetor halves get loose, and then suck air. Kept me from starting the tractor at one point. Tightened the screws and it started right up. So the gasket between the two body halves has some damage to it. I'll need to adjust the float because there's some times where hand starting causes it to flood out. (I was having to hand start due to problems with the starter, starter has been rebuilt and works now). I'm also getting some leaks in the upper portion, and the governor tubes. Though, the governor tubes are leaking oil, not fuel.
Thanks for the info.
Speaking of floats, I just recently had to change the one on my late grandpa's John Deere A for not, floating. Kept flooding the tractor out trying to start it. Put a new float in, and started right up.
Always nice when the fixes are easy.
