Carb has no choke; and the vacuum advance from the distributor is not hooked up. Only thing using vacuum is the brake booster which seemed good...should I redo the timing? Ran fine in the fall with old plugs



If the timing curve is not set right for the combo & is set at the factory timing curve, "NOT" running the vacuum advance is killer, meaning it'll bogg/fart/poo/crappy excell. ect., get the hint
