How much ignition advance timming are you running? I started with verry little advance and had to open the idle screw a bunch to get it to idle. Once I actually checked The ignition timing and adjusted the timing up to 12° to 14° BFTDC. That same idle settimg had the engine just roaring. I have a Mallory HyFire VI ignition system. It has the abillity to program a set amount of start retard. It only affects the timing under 500 RPMs. So when starting, I'm not working against preignition when starting.
