does Stabil work?

I have a friend who is a certified ASE master mechanic. He rebuilt the carb.
on my car this past spring, I had used Stabil over the winters. He took the carburetor apart, and he said it was all gummy inside, from the stabilizer chemicals. He said I would be better off using Seafoam, for fuel stabilizer and storage. Also said to use REC fuel (non ethanol) gas... for best results.
Been doing this since the rebuild, and my Duster runs EXCELLENT.
