Bit of an update on this. I took the head off the villiers this afternoon and I have found the bore to be in great nick the valves are unburnt and the valve seats look brilliant. The piston is picking up a bit of oil on the return stroke but I think it will just be a case of a re-ring. I will just need to source some crankshaft seals and rings. But all this will depend on if I can locate the rubber tyre for the clutch or get mine rebuilt. I have been in touch with a mate of mine who does polyurenthane casting and has said it can be done from polly but rubber will be better as it can withstand more heat. I will just have to make a steel mold instead of a timber one. I was happy to get the mower running but now I want to restore it. If I have to get the wheel re-cast it will give me enough time over christmas break to sandblast and paint the mower body, and repair the catcher.
Cheers Paul
