Hi,
It finally got the better of me. After looking at it carefully with the new starter hanging on one bolt, I drilled and tapped a workable 1/4 " thread for the second bolt. I got the flywheels of both motors with a puller I had fairly easily.I swapped over the flywheels without difficulty. I treied the old cowl but no go the studs are in a different place. I cut out the side of the Classic cowl for the pinion to clear. Pulled the cord and away it went. I had to use the old air filter housing as the Classic fowls the new starter. I was tempted to cut off the protruding part of the crankshaft so I could fit the plastic mesh from the old engine but I resisted as now if I can find a Classic cowl it will bolt straight on still.
All the best
Jeff
