I put this in another thread so maybe more people will see it......Have a 20hp MTGHS which had a elect problem that is now fixed. It also had a carb problem. I sent it in and they rebuilt carb, etc. It runs fine until I am on a side hill with the right side being the downhill side. It then eventually loses power like it's starved for fuel. When I change attitude (turn up/down hill) it revs right back up. This does not seem to occur when on a Left-side down side hill. Does this sound like a float level problem?
