Carb tune

18 March

Plugs still v  sooty after test ride, I've already moved needles down by one notch since returned from NBS.

So decided to check air screw settings.

Start position
RH 3/4 turn out
LH 1/2 turn out.
As these are air screws very definitely on the rich side.

Ran each cylinder in turn and adjusted air screw to get optimum tick over
Finish settings
RH 2 turns out
LH 1.75 turns out.
Idle screws both 3/4 turns out.

Will see how it goes next time out, when the weather is better to spend more time on fine tuning.
