Engine Performance problem
1976 Ford F250 V8 Two Wheel Drive Automatic alot miles

I rebuilt my carb, replaced wires and plugs and cap and rotor a couple months ago runs like a million dollars. Until yesterday I havent drove it for 3 or 4 days and went to start it up and it sounded like a valve was stuck. drove it around the block and it wouldnt idle at stops and it was back firing and had to pump the peddle to keep running. any suggestions ?

Hi there,

I would indeed start with a comp test just to eliminate a stuck valve, do this firsts and report your findings.
