Pot Trimmer

Clearly there are more than one.

And that's the left-handed version. The RHD version comes with a lighter!

Dumb question, Blue, but what are they for?

One is for calibrating the tach's reading against the real rpm. The other two look like trimmer screws but they are simply "suspicious looking" mounting screws.
