Hi,1965 model.Trying to start,kickback & spitting through carb.Sometimes starts ticks over & runs ok.Reckon ign timing too advanced but cant find definitive setting.It does have a blanking plug at the front of the primary chaincase into which a special tool to locate a notch on the flywheel can be screwed ref Haynes.This establishes the fully advanced position,should I set the points to be just opening at that point.I aint got the special tool though !
