Went out riding with the little ones the other day. The machine was running fine, just putting along in second just off idle. I went to go ahead to check the trail and when I hit the throttle it fell on its face. No power at all. It wouldnt idle or anything. I managed to make it home, if you could get the rpms up you could maintain but if you let them drop you were screwed. Put in a different plug but no luck. I have not had to check anything on this cause it has always been faithful. (unlike a couple women I know) Could I have sucked something up in the carb? I am getting about 125lbs on compression. That should be enough to run I would think. I am a diesel guy though so I could be wrong.
