Hi Ian, for my 1937 Model 9 I always use 0.5mm paper gaskets. Plus a non-hardening sealant like Hylomar or Curil, if you wish. My surfaces are in good condition.
Cheers, Thomas

Hi Again

I am making a gasket for the timing cover - has anyone suggestions on gasket thickness (which would effect the distance between the oil pump shaft and its connectivity to the magneto sprocket).

Also the thickness of gasket for the oil pump base brass plate and the timing side cover surface.

I had a complete spare Model 8 350cc timing cover with oil pump and removed the brass plate - this had the original thin gasket.

Your opinions would be appreciated.

Regards Ian
