Jonathan, engine runs fine, when I remove a vacuum tapping plug the engine dies, so I think the vacuum must be fine. The carb and choke were on the engine when I got the car.

Jacmac, yes the choke idle screw which is really hard to get at since it is behind the choke bimetal element.
I read in Holleys literature that turning the spring cover adjusts the time in which the choke plate opens, one way for sooner, the other for later, just havent tried it yet to see if it releases the fast idle too.

Pete, is this the normal practice? i.e. kick throttle fully down before starting to set fast idle, then once the engine is warm kick the throttle again to come off. I had assumed it would come off fast idle automatically.

thanks
