Carb Issue

You didn't mention,if it was hot (weather) when you were driving. Ede's do have a perpencity to heat soak (boiling fuel),when shut off,under hot driving conditions. When hood clearance is an issue,I use the Edelbrock #9266 insulator gasket. This gasket has pretty much eliminated all my hot weather driving conditions. If hood clearance isn't an issue,I use a 1" phenolic spacer.
Hope this helps.

Or yes,you can get a Holley,and be ready to futz with it more than a British motorcycle....:D
