OK my 1995 bayou 220 would only run at half throttle, when you would try to punch the throttle it would bog down. I rebuilt and cleaned the carb, replace both the ducts to the carb and it still wont do anything. So today I took the valve caps off and discovered that the screw and nut to the intake valve were gone so I'm assuming that is propbly the problem I took the top end of the motor apart and found both parts. My question is when I go to readjust the valves what lines am I matching up for TDC I think I'm looking for the little T line when u open the cap above the recoil and then what else am I looking for? I cant seem to find anything to match the round mark on the cam sproket up with.
