Idle problem - sticky choke?

[RiggerRob]

Hey, Tercel Wizards,

Just had my head replaced on my car, kudos to my awesome mechanic for being resourceful and thrifty as always. I took it on its first test drive today and it passed with flying colors - took Town Mountain Road from downtown Asheville up to the Blue Ridge Parkway (about a thousand foot climb), went all the way up at 40 mph in 3rd gear, no overheating, runs smooth and quiet as ever.

The problem: when I let off the accelerator, it 'hangs' at about 2000 rpm for maybe 4 seconds and then drops into smooth factory idle.It does this every time without fail and the engine runs great no matter what. Is this a sticky automatic choke, or is there some adjustment I can make on the carb - or whatever - to shorten this drop into 'high idle'? It's not that bad unless I'm shifting at speed - then it gets kind of annoying.

Really happy to have my T4WD back on the road!

Try lubing the accelerator cable first - drip a LOT of silicone lube into the casing while raised from the engine bay. Be sure to put a paper towel or shop cloth where the cable attaches to the accelerator pedal!

Thanks! Any lube in particular you recommend or just any spray silicone lube is fine?

[ARCHINSTL]

Any silicone lube - spray is a bit messy and wasteful, but do-able. If possible, use a drip type.
Also put a few drops on the pivots of the pedal.

I added an extra throttle return spring INSIDE the OEM one...has to be a smaller diameter and the right length.

Thanks, Tom and Takza, seems like an obvious one now that I think about it. Now that the leaves are turning looking forward to zipping around on the Parkway in my 'new' car...

UPDATE: My mechanic adjusted the throttle stop on the front of the carb and the problem went away. Getting her ready for mountain winter!
