- 1977 light blue
I've been having an issue with E10 boiling out of my float bowl after the engine is warm It's a basic l48, with an aftermarket cam. My 77 has basically the same engine, with an Edlebrock intake. I do not have this with the 77, but I do with the 79. Ive heard the coolant passage that goes under the carb can possibly cause this, and blocking this passage will keep things cooler. I've been running straight RV gas, and it doesn't boil. The E10 has a lower boiling point. Straight RV gas is over a dollar more, and not universally available. Any input as to how I can solve this would be appreciated.
