I'm guessing you don't have a Q-jet with an idle kicker solenoid hooked up thats malfunctioning do you?
That was one of the easiest "fixes" I've ever had on a vehicle. Unplug, dieseling stopped. /forums/images/graemlins/smile.gif

When this happened with my old carbed 1/2 ton I would fill a 2 litre pop bottle with water , warm up the motor and pour it down the carb slowly while reving it up
Being careful not to let it stall out or pour it in too fast and hydro lock it
This works great and is a cheap (free) fix to clean up the carbon that is causing the run on
You may have to clean your spark plugs when you do it

That is a tricky deal with that CCC carb, I bet that your hi idle is sticking. It was last time I worked on the truck with you.
I had the same problem when my K5 had the same fuel system as yours, I fixed it by pulling the complete system along with the motor and put something else in. /forums/images/graemlins/histerical.gif
Just shut it off in gear and it won't do it.

But shutting it off in gear isnt the right way to fix the thing. /forums/images/graemlins/thumb.gif

Have you adjusted your timing lately. Sounds like it needs to be timed.
Or are you running a low octane fuel in a motor that needs higher octane?

I second the timing. Mine used to diesel at 8* BTDC, I put it at 12* and haven't had a problem since. Before you get too far into it, try messing with the timing.

More timing is what makes it diesel acutally.
Set your timing at 4* or where it belongs and set your idle correctly and it will stop dieseling.

9:1 or less *typically* is ok with 87 octane on motors even with junk heads, as long as the timing isn't too advanced.
Backing off timing is easy enough to do, worth a shot.

First thing I would check is timing (make sure to plug of the vacuum advance). check for vacuum leaks. Then check make sure the carb is adjusted right. Oh and quit buying the cheap gas from Arco You cheap basterd /forums/images/graemlins/wink.gif /forums/images/graemlins/tongue.gif /forums/images/graemlins/rotfl.gif
