Best Answer

not getting enough gas due to a couple things.

1 the filter has some stuff in it and blocking the gas that your engine needs when you bring up the throttle.

2 sticking float within the carb same idea the float is not going up enough to allow more fuel again to run the engine at a higher rpm those are the 2 things i'd check
