I just repossessed a 1980 Chevy 3/4 ton and have been trying to get it running decent before listing for sale. It has sat for several years and definitely more of a project than I am interested in. It will idle just fine and rev up in park with no issue but as soon as you put it in any gear it bogs down and pops then dies when you give it gas. I can feather the throttle up to maybe 5 mph but that's about it before it craps out.
I have fixed several major vacuum leaks with no change in how it runs. Plugs and wires are good, timing is good, gas is good. I poured about 10 oz of marvel mystery oil down the carb while it was running and let it soak for a week...no change.
it has a 4bbl quadrajet and turbo 400 trans.
any ideas?
