How do I fix sloppy butterfly ?Well it depends. If you don't get too far into it's not too difficult. Buy a carb kit and some carb cleaner. Pull the top of the carb, change the needle/seat, accelerator pump, set the float level. Make sure the float is good and not absorbing gas. If in doubt just replace it. Spray some carb cleaner thru all the passages and blow a little compressed air thru them. Then just put it back together with a new gasket. Check that all the linkages move freely, that the butterflies open and close w/o alot of slop. Might not be the highest quality rebuild but should clean it up enough to run decent.
