My 914 E production is experiencing a miss above 4500 rpm. It doesn't seem to have hurt my lap times and I actually ran my fastest lap ever with this happening(probably was totally flogging car out of frustration). It happened between sessions with no notice. Shut car off running great and next time out it started. I have checked valve clearance, installed new 009 distr, valve springs look ok, timing is ok(but willing to hear reccomendations),intake and carb gaskets new-Dellorto 40s,dwell is right, bought MSD but not installed yet, bought elec. ignition but not installed yet. This condition causes the engine to sputter from 4500-7000 rpm. I have to short shift or wait longer for the engine to wind up. It is consistent and does not go away. Plugs like new. I heard about something on the carbs that plugs up but don't remember the specifics. Any suggestions would be greatly appreciated. Thanks!!!
