Help! I have a 2004 360 4x4 that was starting hard and backfiring a little. I figured I would take off and clean carb. I put it back on and it was popping constantly and LOUD! everytime I touched the gas. Took the carb to a local Kawi dealer and they were NO help...said I would have to bring in the whole machine. Would not tell me float bowl height. Must have tried 8 different settings, still popping like crazy and still LOUD! To date, I bought a brand new carb, the rubber connector from carb to engine, new fuel in tank and new plug. It now starts good, but now has a much quieter but steady miss when I touch the gas. Is this electrical/ignition or possibly valves???
