Did a bit more on the TAC today.
Had a go at getting the stub of the ground off screw out without luck. Checked my donor mower's pull start, and it was good, so did the transplant.
Was amazed at the new looking condition of the TAC's internal crankcase, zero movement in the bearings.
On the second start up yesterday realized there was small change in the revs with throttle movement so took off the carby inlet, needed an O ring. On the exhaust side of the bore the 'machining marks' are visible with just an indication of piston ware.
Replaced the kill switch rubbers and gave her a run, one pull start and ran nicely through the rev range and stopped as it should.
Looks like it's going to be a cheap refurb :yay:
Having another go at posting bore picture for assessment .
