I had a problem with my carb, opened it up, cleaned it out adjusted everything and the machine started 2nd kick and ran beautifully. I ran it maybe 6 to 10 times (short sessions) and one day I took it out and it ran like crap for about three minutes and died. I let it sit for ten minutes and it would fire up but sputter a bit. The second I give it gas it would struggle then die. So I cleaned out the carb and it ran great. No problem. Got it on the trailer, got on the dirt started the bikes up, and it did it the same exact thing. I assume its the carb, but before I take the carb off and clean it AGAIN I thought Id post this first. P.S. I Changed the plug just for fun, but same story. Any ideas?:">
