Constant misfire ??????

[Bluebird7]

Looking through the complete thread, just one more thing you could look at is compression.

Run the engine up to the point when the misfire starts, whip the plugs out right away and check the compressions on each cylinder. I don’t think it’s a sticking valve, because that usually happens when the engine is cold and they loosen up when the engine has warmed up, nevertheless, I think a valve isn’t closing properly.

It’s an easy check…don’t lose the faith, it is something simple and can be fixed!

Good call, will try that too.
