last night i had a problem with the clutch not working. it was as if it was not grabbing. i took the cover off and everything looks good so far but i have not torn into anything as of yet. it was working fine all night no slipping or anything, the motor did not want to idle low even with me backing the idle screw on the carb down a bit. also it stopped working while it was idling and we went into the garage for a few mins. what would yall say to look for?
