Pablo. It sounds like you may have a vacuum leak.. But it could be a carb problem. You said that the engine has some trouble when cold as well.. what kind of trouble

When starting cold, it will go into fast idle after one or two presses of the gas pedal, although it generally dies the first time and need to start it again. After warming up for a minute or so, it will generally hold an idle (when the outside temp is in the 30's or 40's). If I only let it run a fast idle for a few seconds, it will have a hard time.
The vacuum leak idea makes sense, although it would be intermittant. The anti-diesel solonoid is there to create a massive vacuum leak when the key is shut off, so that the engine has no choice but to stop. Could it be operating correctly only when starting cold, but not other-wise and creating this problem? Has anyone replaced one of these without tearing the carb apart? I have no intention of rebuilding any part of this car, and one hour of shop time is 10% of the value so it is hard justifying a trip to a mechanic. Thanks.

but the anti diesel soleniod does not work the way you descibed.
I believe it shuts the fuel flow off to the idle circuit, thats why it can not "run on".
I got this from studying a blowup picturs of a Hitachi.
As for your problem, sure sounds like the age old problem with the Hitachi
(which you have - unless someone changed the manifold and carb)
this problem is worn throttle shaft bushings.
Sorry replacement carb seems to be the easiest fix

I have mostly seen this on the POS Holley 5200 Weber clone once endemic on Vegas, Pintos and Chevettes, but any carb that is 20 years old is likely to have some wear issues.
