Boyer Electronic Ignition Suspect

The trick to sorting out if a misfire is carb or ignition is to mark the throttle, 1/4, 1/2 and 3/4. Then go for a ride and note the throttle position/revs when the misfire happens. If the misfire happens at the same throttle opening regardless of revs then its carb, at the same revs but at different throttle openings means ignition. Not hard and fast but 80% reliable.

I found 2 issues at once sorting a misfire .... first was a squeezed too tight coil .... got new German made set thought all good .... nope, dug into older Boyer found cracked/broken wire on pickup ... installed new Boyer MK4 ..... been all good last several yrs now .... got to look at everything one at a time to have your eureka moment ....
