Hi! I’d agree without pulling everything apart it sounds like a carb issue. definitely check for blockages in the low-speed passages. I’ve had similar issues with miss-adjusted floats. If the float isn’t performing correctly sometimes the bowl won’t fill up enough to allow the weak low speed suction to work properly. operating a half choke will increase the suction to pull fuel. I’d also check to make sure your needle packing… a complete go-thru of the carb before you start chasing other possibilities.

A little information is a dangerous thing!
