Ball on the manifold? I was dicking around with idle before my IP starting pissing everyplace and it was pretty bad when cold or there was a lot of load from the alternator. I think the best idea is a hand throttle so I could pull on the throttle cable and set it just a wee bit higher if it when cold/etc. I've been meaning to put a kill switch in for the IP solenoid, and a 5speed, and a refreshed engine, and etc...
