In trying to identify the type distributor, it was suggested to call Langdons Stovebolt in Michigan. He suggested checking fuel pressure at 50 MPH. Went to auto parts, rented gauge, purchased fittings, headed for home in the old truck. Halfway home, wham, it starts running perfectly. I was telling the young kid at the parts store my story and he mentioned that sometimes if you overfill the gas tank, it plugs a vent tube……….now that you mention it, this started shortly after I let the nozzle click off on its own which I normally don’t do. Is this 20 year kid on to something? ( The tank is now 3/4 full after all the messing around)… Anyway, it runs great again, my valves are spot on, my carbs are adjusted,
my compression is OK , I’m more familiar with the truck and “feel a little closer” to the old gal..
It does have the Pertronix distributor which I’ll be changing out soon.. Thanks for the heads up..
And again, thanks for the help. Hope this can possibly help someone else down the road even though it’s not entirely definitive .
Take care
