Like many, I'm struggling with adjusting to ethanol content fuel. I've seen fuel filter gaskets turned to crumbly bits and suffering from vapor lock. I've solved the vapor lock by shutting the pumps down before I turn off the car and adding a phenolic block to the carb (Edlebrock four barrel). But I'm struggling with off idle throttle performance that simply isn't a crisp as it used to be.
I spoke to the fellow that built the engine and he suggested that I go one step richer on the jetting and advance the timing from 34o @3,000RPM to 36o. Midrange and up is just fine now that I've gone a little richer but low end isn't as clean. I haven't as yet changed the timing.
Has anyone else adjusted the timing to address this?
