You could experience this problem with old gas (I did on my '70, it gets driven maybe 500 miles a year since I got it, and less before that), but that doesn't seem to be your issue. Guess I'll try SeaFoam in my truck and my Skylark, which also ran like crap after sitting for many months. Gasoline ain't what it used to be.
