Re: Vac advance?
Tark,
Are you sure the timing is good? Every time I have
experienced your symptoms, it's been retarded timing, and I
needed to keep the revs up to get the mech advance to take up the
slack. You just may have slipped a tooth on the timing. At
least that is what mine did, before it took a crap on the
highway. Low probability though. Check the plugs too. Fouled
plugs can ruin your day. Everything else in the truck is ok?
Maybe you have a bad gold-box? Sounds weird, but I would avoid
neutral drops at all costs.
Dirty carb could always do it. When you get off the idle
circuit it runs ok? Sounds like my T'all TQuad on a cold
morning. I have to pump like a mad man to get it to accelerate
without dying.

Yah,
Its seems more and more like I might have something trapped in the idle
circuits, but it will idle ok, its just when I shift into gear. The load is
too much for it to take. I know the accelerator pump is good. On the other
hand, I was nuetral dropping to get it going, worked the best, still not good
though. I will pull the distributor and clean/inspect it as best I can...
Before I try any of this though I will change the points, the condensor, cap,
rotor, and wires trying to run it after each step to see what happens. I
have known this engine for about 10 years, never to have had any major
problems except for a slight rap which is at this point the least of my
worries. It probably has about 300,000 mi on it. If I can't get it
straightened out, I will swap in the '77 engine, that one is all set.....
