@venture32os:
I think (hope!) I got it all out, it was mainly in one finger. Of course my finger looks a mess since I finished!

@pilot77:
Sorry you met with the ground too - I hope it didn't hurt your Shuttle too bad?

My engine (OS32) runs pretty smooth at the moment, but it did run badly shortly after run-in. My LHS guy tweaked the low-speed needle and since then its been pretty sweet. I'm afraid I don't know what the actual settings are. The high-speed adjustment is around 1 turn out IIRC. I usually adjust it a couple clicks according to the conditions to keep it smooth.
