Ok, got a guy here (I've forgotten all my carb knowledge) that has an old 302 "Cobra 2" with an aftermarket Edelbrock 289? intake and an edelbrock 1405 carb. It ran fine on 87 but he put 93 in it and it runs like shit now. Would that be timing? Should be bump the timing a degree or so?

Believe nothing you hear and half of what you see.
I'ld remove the fuel and start over. He could have got a bad tank of fuel.

That's what I thought too. But going off of combustion theory though, timing isn't as quick and adaptive as an ecu controlled car that monitors everything. If his timing's set to just pedestrian levels for crap pump gas, would the anti knock properties of the higher fuel make it harder to burn enough to cause rough idle and rough driving?
