[TR] Missing at high revs TR4A

[Chris Buckley]

Hi List,
  I am using stock manifold with PCV valve. The engine is not yet fully run in. I HOPE it doesn't need new rings already. If a new plug doesnt solve the problem, I will do a compression test.

Are you using the stock manifold with PCV valve intact? If so,
then the #3 is where the oil blowby will be deposited, causing soot
and eventually wet fouling.

You can, for a while, help the problem by running a hotter plug
in #3, but you should be planning and saving up for rings.
