Does the timing not affect the O2 in the exhaust at all? I.e rich/lean?
Anyway, I adjusted the advance and retard to pretty extreme in either direction just to see that my timing mark wasnt off or something but it made no difference so I set the timing to where the engine runs best. The carb is adjusted correctly with respect to rich lean.
The car came with an engine driven fan without a shrowd which I have tried since this problem started again yes. Thing is both set ups have worked old and new.
