That would be the other way round, then you would have virtually no compression.Is it possible that I may have put a low hole Piston on a high hole Piston arm?
I mean would it fit... I seem to remember checking the Piston height before I put the head on the barrel and the Piston came right up to the top.
It has to be the way that I skirted the Piston to clear the intake port.
It's the only modification I've done to the engine.
If you had the mag off, then check that you put it back the right way. The key should be at the 1 o:clock position @ TDC.
