Thread: Dieseling 350

Tweet

I have a chevy small block 350 with rhs pro torker vortec style heads, a comp dual energy cam with .462 int., and .482 ext. I also have a holly 650cfm carb installed along with headers. if you start the car and get it warmed up it continues to run un after you turn of the key. If it doesn't get warmed up it turns off like a normal car. I was wandering if anyone would have some light to shed on this dilema of mine.

Put 12-16 degrees initial lead in at the crank. Curve the distributor to add additional centrifugal lead to total 34, all in by 2800.

Dieseling was such a problem with the hot-running, low-compression motors of the early 70's that the OEM's installed dashpots (electric solenoids) on the side of the carbs that, when the key was turned off, the solenoid relaxed and completely closed the throttle blades. When you turned the key back on to start the motor, the solenoid energized and cracked the throttle blades open to the idle position. If the motor can't get fuel/air, it can't diesel.
