Smoking engine

[Ian Williams]

I have experienced suppliers providing the wrong size rings in error, even if they gap up correctly they don't appear to bed in and subsequently the engine smokes, some ring sets in the past have been of questionable quality as well. Deglazing the bores and a new set of rings has solved the problem for me, even quite worn bores can run without excessive old consumption with a decent set of rings, and no I am not talking about those dreadful cord rings with the serrated centre! Unless you can find another cause such as the valve guides (possible if unlikely), you may need to bite the bullet and start again with new rings, I never use the baffles either and with good rings I don't seem to experience issues.
