I'm with Airhead, vacuum tap with no off position, if you have 2 pipes going to the tap from the tank then it's a vac if you have one pipe going to the tap from the tank then it's gravity fed.
Hi Paul, well most of your questions I have no answer for but APE HANGERS I do know about, if you want rain to run down to your armpits then fit them by all means but they look cool for about 5 minutes then you think "WTF was I thinking?" make the bike hard to handle and your fingers and wrists lose the circulation after about half an hour. If you live in California then by all means go for it if you live in the UK your going to feel a right twerp on a wet Monday in a queue of traffic. Just sayin!
Airhead and NSD have good points but I would find out why the choke has no effect on idle speed? it should at least up the revs a bit, might be a blocked slow running jet. I know you had the garage clean the carbs but if they didn't take the jets out then they didn't really clean them. If it runs fine and starts fine when it's warm it has to be a slow/cold running problem in my opinion but either of the above could be a good starting point.

Lassy, just a thought but had a similar thing on my FJ, changed both coils and never had it again. Think your best bet is to do the same. Is it on all 4 or just a pair of cylinders?
