Silver Century not starting

[Charles uk]

That's a very big increase for just a hone, new rings & an early head or did you skim the top off the cylinder?

No skimming done by me. Just sealed the head-gasket-cylinder meticulously. It was a secondhand replacement piston too, which I polished up. My first reading was done while engine was cold as it was a non-runner. Second reading was taken straight after a ten min tank run. Just pulled it over 3 times with tester attached. I was running it 10:1 with quicksilver premium.
Needless to say I’m very happy with the 70psi reading.

I have a project, now a bit old that started out with outstanding compression........then I played with the head a lot to get 92psi at the end. Gasket and sealing not copper gasket any more etc.

The original head on it was visually "a thin casting" when viewed side on. I have no idea why anyone would have machined it......it presented surfaces like any other BS head.

I should drag it out and continue the old thread.........later.

Have you compared your head dimensions with any others?

Interested aye.

Good work and
