Hi, my q has developed a bit of a misfire which happens under high load (3rd or 4th at 1.5 -2.5 RPM, 3/4 throttle) where it starts to stutter (no running on all 5). Any idea what this might be ? It doesn't always happen and if you dump the clutch it rev's without missing a beat. Could this be caused by the vacuum advance not working properly ?
