Re: Hard Starting - Where to go now?

Mark, I agree with Harry and even though you have set the timing I would at least see if the following eliiminates the problem or has an affect on it. First scribe a mark on the distributor base and line it up with a consecutive mark on the engine block. Once you run the car up to the temperature where it gets hard to start, loosen the distributor just enough to allow it to rotate a little each way. Rotate it while someone is attempting to crank the car to see if it starts with the distributor in a different position. If that doesn't work, line up the marks and tighten the distributor back down. From there I would open the throttle by hand while looking down the carb throat to make sure that the accelerator pump is pumping fuel. If it is then cup your hand over the carb throat while someone attempts to crank the car and see if it starts using that procedure. It sounds like you've replaced or rebuilt all of the critical components and checked the most likely causes but how about vacuum? Have you hooked a gauge up and checked it?
