i was possibly thinking the vacuum advance mechanism might be causing a vacuum. if the distributor is as old as the engine then the rubber diaphragm may be bad. anything is really possible with old trucks.

So you're saying that the diaphragm may have busted causing a leak?
As for the age, I've no idea, it looks old.
Like everything else on this engine. lol
I am almost tempted to get some new hose and hook it up to manifold vacuum.
ya. it could be. new hose might be a good place to start but i think you may want to see about getting the pickup moving with vacuum power. if you can get it moving you may see better performance out of the engine.
I guess I'll end up getting new hose, and running it to the vacuum tree on the back of the manifold and seeing if that works.
When I'll get around to it, I dunno.lol
