balooba, I had one many years ago that was giving me much same problems that you are having, it would run farily good but when you moved it just the slightest bit it would start running terrible, similar to flooding, what I found was that they person that owned it had removed the rubber bushing that is on the top of the carburetor and when he put the filter back on did not put it and tightened the air breather screw so tight to hold the filter housing on that he pushed the hole where the threads are so deep that it cracked a hole in the top of the tank, that is a blind hold, meaning where the threads stop is where the hole ends, not open into the tank, that very well could be a lot of your problems, nothing worse that something so simple as those can get so complex, good luck, Joe
