Hi guys I just picked up a 02 original tires,no mods low hours, carb was overflowing and owner adjusted the floats. I cleaned the cabs and checked all the jets and did the float mod to the tang and the floats had to set a 20mm or the carbs would overflow. Also installed new spark plug and checked parking brake and reverse limiter switch. The quad idles good and will pull top end good but 1/8 to 7/8 it spitts and backfires even when sitting still. Have I overlooked a passage in the carb or is it an electrical issue. Im planning on cleaning the carbs again in case I overlooked something.
