try a hotwire to the coil
and after a hesitant start, she ran well and revved too!
(the light switch was incorporated when 'moi' wondered how the fuck, if she did start, I could stop her)
and check the compression
big numbers with pete kicking and me holding the tester (not the screw in type!)
Both 140psi and 120s with throttle open.
Later returned to original switch / wiring and she stalled when under load
letting clutch out to test ride.
