Ok, it idles down now! Turns out the fast isle can was getting into a bind. Cleaned and lived it and now isles down find. The only thing now is that it's still a little too fast for my taste- around 1100rpm. Any advice on how to get it lower, or just leave it?

Ggzilla, got any ideas on how to fix the high idle? This isn't something that has gotten worse over time. One day, it was fine, the next, it wasn't.

I checked it out today, and I wasn't able to replicate what happened in the past. It started fine and ran smoothly despite the fact that it won't idle down. Also, it appears that the choke was operating correctly as well. I tried spraying carburetor cleaner with no improvement. No vacuum leaks as far as I can tell, because I individually checked all the lines for cracks and tears. It kept running when warm, but still around 2000-2200rpm. I let it run for probably 30 minutes or more and did some yard driving. It never idled down to normal or died, which I find strange because it used to die a lot. Someone said earlier that this idle-cut solenoid prevents dieseling as well. Well, after I turned the key off, the engine began dieseling slightly for several fires. I just wanted to get y'all's opinions one more time before I go buy a $60-$70 carburetor part. Thanks for your help again!

Hi there! I am a new member from the Upstate of South Carolina. I have a 2 owner 1984 Nissan/Datsun 720 Pickup. What a great truck! It has lasted a long time, and with a little TLC should last even longer. I am trying to get it back on the road at this time but am having some issues getting it to run well. Right now, it will start easily from cold and rev up to around 2000rpms immediately. It runs fine when cold, but when it warms is a different story. As soon as it gets warm, it immediately shuts off and is almost impossible to get running again until it cools off. Any ideas as to what causes this? I'm thinking either some kind of temperature sensor or a clogged jet in the carburetor? Thanks. It's a 2.4l engine.
