My 1989 Toyota Corolla (Carbuerated) was running rough, i put new plugs, wires, cap, and carbuerator rebuild kit on as well as changing the oil. runs good now but when the engine is warm and i go to shut it off it runs on for a few seconds. I tried two different brands of cleaner to clean carbon build up out of cylinders, both made the car smoke really bad for a couple minutes. Should i try this again to eliminate run on, or what should i try?

The problem IS NOT your starter.Just like some of the other ones say it could be your timing is advanced a little,or the idle is set a little to high.If its a manual trans idle should be about 750 rpm,if its a auto trans it should be in Drive with the em brake on about 750 also,if the idle is 850 or higher set it down to 750 then turn off the ign.to see if it stops running.If it still runs a little then check the timing setting.The other thing that could cause it would be a vacuum leak,maybe it came off when the carb was off the car.You may have a vacuum hose that is split causing just a little vacuum leak.A vacuum leak will cause the idle to be higher than normal.
hope this helps

It may be idling too fast, also.
Yes, I would run the cleaner through the engine again. A small piece of carbon anywhere in the cylinder will glow red hot when the engine is running. Since it will still be red hot when you shut the engine down, the engine will begin to "diesel". The hot carbon will act as a "glow plug", like in diesel engines, and cause the motor to try to keep running. Good luck. Pops

I suspect this is the result of your carb rebuild. The thing is probably idling too fast. That is most often the cause of run-on. You can check this by stopping your car, and with it still in gear (and with your foot still on the brake), turn of the engine. THEN put it in "PARK"
This will eliminate the run-on (usually)

You didn't mention replacing any belts. I would check my timing,
ignition switch/cylinder, and starter. Are you buying Toyota parts & filters? This makes a difference-especially on the plugs. I also believe the 'theory' of buy higher octane gas & only a 'real' brand-
not at Kroger, Wal-Mart, etc.-whose gas is it anyway?

It sounds like your ignition timing is set too far advanced, it will run on especially in hot weather. You may have to go to a little higher octane fuel if that does not work. Another indication of too far advanced timing would be pinging noise in the engine when you accelerate..

replace piston rings and maybe fuel deposits built up on the valves choking the air/fuel flow replace spark plugs distributor coil cap and rotor

I would take it to somebody who knows how to fix it. Like maybe an automobile mechanic.
