Thread: Engine runaway!!!
05-31-2009, 02:31 PM #1
Was working on the ol' slt and the engine took off, pull lanyard, still going, choked er to death, or ran outta fuel?
Didnt do it but for 20-30 seconds. Never reached to high a rpm but.... Top end looks fine. Only thing I've done different lately is changed fuel filter and had the heads off. Head gasket leak cause this? I asume air was leaking some where. Kinda scary, like "Call the Excorcist!!, Poltergiest, Whatever". Fweaky man I tell ya.

Usually the Death rev is from an air leak.
It's not the first time I've read about the kill switch not working though.
Something was so hot inside the combustion chamber that it was "glow plugging" and didn't need the spark from the ignition system.
You did right by choking it out.

If you just changed the fuel filter it might have been a air bubble causing a lean condition.

This is my bet as well.
Everytime i work on carbs/fuel lines. I'll crank the piss out of the engine before applying spark. This will verify all fuel passages are primed up and ready to rock.
I also initially start-up with top of carbs exposed and 2 cans of fogging oil If she starts to runnoft on me, i'll douche it with the oil, and if a second guy is handy, have him hold the throttle full open, with choke ON.
I still don't get how it works, and never believed it when first told to try it, but several times, just applying full choke, and then holding the throttle to the bar will tame it down.........sounds weird but has worked.
I will never forget my first experience with one though! Helpless feeling and you know that just shutting the fuel off is a BAD thing.
