Phil before doing anything else, remove the dizzy cap, spray inside and out with WD40, wipe clean, spray again and refit.
Mine did this today, I found it was condensation inside the cap from all this humid weather. Was fine this morning during a short run, then started doing this when almost home.
It would start OK, rev fine in neutral, but under load would misfire.
Thanks Doc. I did actually give the cap a spray and clean just as a matter of course when I tested the leads and thinking back I reckon that may have actually been the cure.
When I was having problems I moved the timing light pickup to each lead and they were all firing inconsistently. I didn't realise the timing light only strobes when there is a spark.
Thanks again Doc and Co.
