You may have leaky throttle shaft bushings. Check them for wear. I
assume you have the high idle while the idle screws are removed. Somehow
you are getting air into the engine, so if it's not coming through the carbs,
it's a significant vacuum leak. What's your PCV system look like? Do
you have a good manifold-head seal?

What choke you use depends on exactly which carburettors you have
fitted. Are they H4's or HS4's? The H4's I had on my 1296 street motor
didn't have any choke for 9 months because I didn't have any good ideas for
6 months (I was lazy the other three). Tell us what type of carbs you have
and I'm sure we'll be able to help you figure out a good choke solution.
