: I have new fuel pump, hoses, gas tank, cleaned the damper valve, new plugs, points, dist. cap etc.
: Any thoughts. As always, TIA.
I have a 74tii also. Make sure that the warmup regulator is working when the engine warms up. The "Hat" that pulls down the richening lever should not be touching the lever when the engine is warmed up. If it is then maybe the regulator is not operating or not getting warm coolant flowing through it.
I had the opposite problem where the engine was running crummy cold but was fine warm. Turned out that my warmup regulator was set too rich.
