hello,ive a 1980 25 hp (serial no. 5705532),ive finally got the right spark plugs ,but what on the ignition side ,if needed ,can be adjusted as it doesnt seem to have contact breaker points ,thanks piperdog
Your engine is a 81, strange that it's the first built of that year! There is no real ign tne up there are no points and you could check the timing As far as the sync and link crap if the owner don't tinker it up it don't change on any of the ADI ign systems.
