Hello!
A 125 main jet and the needle at the highest position raised a little higher by use of a 3mm inner diameter flat washer (0,5mm thick) below the circlip, no change of the idle jets.
The idle screw 3 turns out.
That is the carb position of my electra with 1950´s Hitchcocks exhaust.
Did you baffle it? Without baffle it´s a little bit too loud, I think!
Regards
Chris
