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???

I would check the exhaust valves.. They have to be done about 100 hrs.. I have one with the same thing.. Going to adjust the valves this weekend

Your original problem was/is the valves; they are too tight.

Thanks guys!

The only problem is why would it start popping very loud and constant at the exact time I started playing with the carb? I will check valves though...is there a link for step by step directions on valve adjustments? Do I need any special tools?

pull the spark plug how does it look?

it was a new plug....

Pulled plug and after maybe 4 minutes run time, it's pretty black, looked wet and smelled of gas.

sounds like your choke is sticking.is thre a choke on yours or is it a enrichment system?

 

[novass]

do a search on valve adjustment
