Motor is a 2 stroke and compression seems to be fine judging by the
way it feels yanking the starting rope with sparkplug installed vs.
removed. Agreed on the starting fluid ability to light off on a weak
spark. I just feel something in the ignition system is laying down
when warmed up from engine heat or activity in the component. Not
unusual for electronics to "open" when warm but work seemingly fine
when cold. Have a Clymer repair manual on order-hopefully it has ohm
checking values for the different ignition components. This motor been
doing this crap for years-so now it will get fixed. I never been a big
fan of electronic ignitions-at least with a point system you can carry
the spare parts in a trail bag and get back home.
