Hi Grumpy, sorry i havent gotten back earlier bit busy. Did check out both flywheels as suggested and the only difference was the size of the centre hole taper end that is closest motor, other then that magnet was same size same spot, virtually identical flywheels. I made up some black pva glue and spread around taper on crank put on flywheel with a medium amount of pressure, took off again and all of taper and centre hole on flywheel were clean, except for minor nicks that come from years of use. I started small first by attaching oil pump and starting, ran perfectly. Repeated 3 times just to be sure. Put on chain, bar and side cover and with my toes crossed started it up , idled perfectly, gave it a quick squirt, back to idle, repeated, repeated turned it off. Checked everything, all okay, repeated reving, idling a number of times, all is good.Could i please ask you to explain what was actually happening here, can kind of understand but not seeing the full picture..
Thanks heaps Grumpy.
