I have a mechanical choke, but i feel its not responding very well, dies on me almost instantly when closed.. High idle is setup after sound, don't have a rpm gauge, should get one tho..
The AVS is a good carb but you can buy an electric choke to add to your Holley. As other have stated I'd get things sorted on the ignition side, then get the idle set and move to the choke. A dial back timing gun with a built in tach is really handy. Ad a vacuum gauge and a volt meter and you'll have most of what you need to get this tuned up correctly. Don't throw parts at it until you diagnose its a problem.
