Got my 650ss running alot better from a good carb clean, but i had a sputter at quarter throttle now, if I give it more gas it clears right up, but hold it there and it just sputters and misses, last check on plugs n they look fine. Any help would be great, thanks again

Maybe a pilot jet or float level

Both check out fine, I'm almost ready to buy another carb, tuk tuk says he uses a better carb, anyone know whats different?

have you tried richening up the air fuel mixture at a 1/4 throttle you should still be running off the pilot jet in carb,might be a hair lean.
not sure what carb you have but this happens on the smaller buggys if its a little lean on pilot jet side of carb.
