Float level and drop are extremely critical on 4GC carbs. The float chambers are so small that if the level adjustment is even a little bit low, the bowl gets sucked dry on full-throttle acceleration, and the engine bogs. Slightly too high, and it floods. The gummy residue at the bottom will definitely glue a float down if it rests on the bottom of the bowl!
