Sounds like you have a carbon track in the cap from a soft brush.Check that the contact plate is not above the rub area shaving off the carbon and clean with some scotch brite.Also not sure what carb you have on there but on the Ace I saw this weekend it had a wild little gear that pics up the power needle?as the throttle is rolled on check that out also .Good luck Ian>>>>>>>>>>>>> ----- ORIGINAL MESSAGE FOLLOWS ----- just finished a major rebuild on 22 Ace start from cold runs perfect and smooth as it get hot say 5 minutes starts to misfire when you open the throttle it's flat won't pick up. The mag has been rebuilt by a very well respected company,has new HT leads, anyone else suffered the same problem ?
