[QUOTE="Big Sid, post: 39277, member: 2781"] Sid here . About engine roughness . External factors enclude detonation from overly lean mixtures and ignition timing being too far advanced . Many magneto cam rings produce undesirably early firing on one lobe resulting in detonation and need stoning to bring this early point break into an acceptable range . Few bother to check the timing on both cylinders so this escapes notice . It's best to retain the late breaking lobe and instead Dremel down the earlier contacting lobe to acheve the timing desired on both cylinders . Polish off the rough surface afterwards to eliminate rapid wear on the fibre heel , and a tiny touch of grease here is wise , on both lobes of course . [/QUOTE]
