Hey all, trying to work out some issues on my 340. has bad detonation / igintion sounding knocking. i did not build or know anything much about the engine. Has a holley carb, mopar performance high rise intake. I've changed plugs, timing, fuel, etc. i noticed that when i spray carb cleaner at the base of the carb to manifold gasket it wants to stall so i'm guessing bad seal/ vacuum leak there. does anyone have any other ideas for me to check where its coming from. its from idle to like 3000...
