....I have to put a rag over the carb bell mouth when cold starting, what's likely to be the problem?
A mate of mine suspects an air leak, as I suppose by using the old school rag method, I'm effectively restricting air intake. Would I be correct in thinking it's non electrical, as it does fire up virtually 1st or 2nd kick with the cloth, but can be any number without.
Basic set up:
Avanti with 30mm phbh.
70 choke
54 pilot
Av266 atomisor
X7 needle 2nd clip from top
45 slide
Air mixture screw currently 2 & 1/4 turns out (but no difference when 1 & 1/4)
17 degrees static on 120W stator
Mid weight flywheel.
Any ideas?

You are right about it not being electrical by the sound of it. The pilot seems a bit small, my Avanti had a 55 pilot and I think Ron suggested that a 58 was a preferred size. Also make very sure that your choke is opening fully, there should be only a little slack in the cable when it's in the closed position. An air leak is also possible

puzzling mine has the opposite, starts first kick, same carb set up

The additional 10 stone you use on the kickstart may be a factor

So what was your excuse going to cleethorpes then
