FH - carburation

 For the record, at the 500 mile service I have changed the carburetter slide on the FH for one with a #4 cutaway.

A #3 1/2 was previously fitted, and the plugs were quite dark.

It's still got a size 30 pilot jet, and for the record, the pilot air screw is about one quarter of a turn out. Perhaps I'll go to a size 25 pilot jet?
