Not sure if anybody is interested, But an update, Thought the slow running was a bit wooly.
So hand cut the slides a bit !!, Maybe a bit too much.
Now have a bad misfire, I would have put money on Ignition, I would have lost !!.
Checked the Rita out and fitted new coils.
Took the rear carb' apart , Good clean.
Lifted the needle one notch in the rear, It was the rear plug, Wetting/Oiling ?
Fitted both starter jets, Now 35, Was 50.
Now have a fast idle with the chokes on.
Still not nice, Made the pilot richer to try to overcome having taken too much off the slides.
Now 1 turn out.
I find the pilot setting affects higher up the range than I thought on Mk2 s.
Slow running now nice, Which makes such a difference with the standard clutch, To put into first gear.
Just been for a ride, best ever !, 40 mph so smooth + roll on from there, Goes like stink !, L/ning spec'.
Cheers Bill.
