The idle speed goes down to about 350 r
so I can turn the idle speed screw down to about 350-400 rpm then it dies. But yes I turned the idle mixture screws in until they stopped, and it stays running, doesn’t effect idle speed at all. The choke does open on its own all the way. I disabled the spark at each cylinder, and found cylinders 1 and 3, the engine runs noticeably worse, all other 6 cylinders, the engine runs exactly the same when they’re disabled. There is a pretty hot spark at each cylinder. This is an all new ignition system, this is the only vehicle I ran it on.
