Engine diesels, misfires when idling or engine braking?
So I know it's a Magnum engine, but I've got a LA ignition system and LA Carter AFB carburettor on it...
When the engine gets warm it diesels when I shut it off. one guy said the heads might have a little carbon on them?
Also, when I engine brake, put the engine under a load, or idle it (idling problem occurs only when warm), it misfires, and it seems to me like it only occurs on one or two cylinders. I know when I dropped the engine in, I pinched two of the spark plug wires, but they DID fire so I figured they were okay, maybe not?
Another guy suggested I run my timing a little more advanced. I'm sitting at 11*, maybe I should try for 15*?
