After it developed a misfire,I set up the strobe and found the dizzy needed to turn about 1/4" anti clockwise(cant remember if thats advance or retard at the mo')to get the timing marks more or less lined up. But it ran well before the misfire and ticked over steady,so summat was/is amiss!
anti= retard, ive retarded mine 1/8" and its alot better hardly any slap now, maybe needs another tad retard but ile carry the 11mm spanner with me and have a play, also done away with the vacume pipe and blocked the the carb and dizzy ends.. happy so far may even seem a tiny bit pokier but im happy to rev a little more now theres some mileage on the clock.
what your temp gauge read rod when shes fully warm ??
