I recently ran into a problem my truck a 1969 C10 started blowing oil. Answer replace head gaskets. Once that was done I fired up the truck to adjust rocker arms and timing. A new problem showed my oil was full of gas. Since I have an electric fuel pump the answer was rebuild the carb. This turned into one hell of a project. The carb was so nasty I did a 100% tare down. I played hell getting all the linkage together correctly something even Edelbrock tech support couldn't help with. Now the next question is how to set up the mixture adjustments for first time startup. Any Help out there?
