Does this when I shut the engine off, altho' not 100% of the time. What does the dieseling (if that's what it's called) mean? It's annoying and probably not good. Non SPFI '86 GL, 5-speed.

hot spots ie carbon build up (oil consumption)  glowing causing pre-ignition dieseling  (run on) as well as a faulty carb / too much fuel (too high idling speed) helping to cause this and possibly incorrect ignition timing.

also the use of low octane fuel in a high compression engine can cause this too.

Is this a new problem ? Was anything recently done before the problem began ?  A little background can help define the problem source.

"subnz" hit it exactly right.

If you don't want to fool around with fixing it you could just get in the habit of killing the car with the clutch then turn the key off.

I mean, by all means you should fix it but being a 30 year old car I could see the hesitation in putting money into it.

Checking the timing and adjusting the carb / installing correct idle jet isn't very expensive though.

If you have heavy carbon build up there's a few things you can try but the right way is to pull the heads and clean the valves / piston tops.

No. it's not a new problem. I'm pretty sure the carb needs adjusting. I don't work on cars so if there is someone in SW Washington that can fix this for I'd appreciate it. I can pay a bit.

 

If I had the money I'd pour it into the Sube. Get the AC going again, put on new struts, replace the valve cover gaskets, re-do the front end (pretty minor stuff), and replace the headliner.

Wasn't there an anti run on solenoid on some of the carburetor versions?

yep the original hitach that would have been fitted  had this

I've heard some Webers also have the fuel cut off solenoid but I have no idea which ones do.  I haven't come across a 32/36 that does.

With out the cut off solenoid it will always do it. It's just a matter of tuning (timing + carb tuning) to keep it at a minimum. My 2 webered '85 and ' 84 do it but rarely.

First thing I would do is run some higher octane fuel for a while to see if the problem is being caused by cheapo gas.  You might solve your problem by better fuel.

Here you go. I hope this helps. Weber DGEV 32/36:

Thank you. I bookmarked that page. Not cheap, are they? Where does that gizmo fit on?
