So I settle down to clean up the cases prior to assembly, and  put cams and followers in to see whats what re bushes etc.

I notice that  the tappet feet do not contact the base of  the cam by  several MM, that explains the  loud clatter  I had since cams were  refaced, so  the only way to solve that was to take a bit off the crankcase guides so the stems can sit lower.

Put it all on the gas ring, blow me if I did not spot two more cracks, one under the timing chest, the other by the tappet guide.

Looks like tomorrow I'll bite the bullet and use that wonder alloy solder I bought at Netley the other year;at least they are only small cracks.

Seems I got sub standard casting on my model 1
