My old carb on my 1951 GMC, with 270 motor and WA-1 Carter, seems to be getting a bit more bogged down these days. I haven't cleaned it since I bought the rebuilt carb 7 years ago.
Question: what gas additive should I use to clean the fuel line and the carb intake/jets?
Or is regular Chevron gas enough?
