My chundercat has had a very minor misfire for almost the entire two and a half years i've owned it. Not bad enough to really go to town on, but mildly annoying. Changed plugs, ht caps, ran fuel cleaner and carb cleaner through, tappets and carb balancing did nothing. Stopped short of shelling out for coils though.

Fixed the problem this evening, by pulling the ht caps off, snipping about 5mm of ht cable off the end and reattaching ht caps!

So all along it was an HT problem, but as simple as a dodgy broken lead.

Glad you got it sorted great

Not a broken lead: all plugs sparking fine, it just seems that the cores were a bit mucky and knackered at the ends of the leads where the caps screw in.

It's still misfiring a bit, particularly around the 3k mark, but much better than it was.
