Choke light stays on

Yes indeed the choke being closed even a little will cause this. Replace the choke cable and stop your problem. After warm up the choke should always be fully open.

Look at this forum for tractors.
I hope it helps you!

Another thing that can cause this is the carb. It may be getting too much fuel once it's warmed up. An engine needs more fuel when it's cold than it does when it's warm. Cold engines run inefficiently so they need more raw fuel to fire-up, and stay running. This is all a choke does. A choke plate closes-off the air going into the carb which makes the fuel mixture really rich so it can run. Less air = more fuel. You'll also notice that cars with chokes also idle real high until they warm-up. This fast idle and the over rich mixture (due to lack of air), allows the engine to fire up and stay running. As the engine warms-up and starts burning fuel more efficiently, the choke plate begins to open, which slowly lets more air in and leans-out the air/fuel mixture. Once the engine is warmed-up, the choke plate will be wide open allowing the carb to run as it is supposed to with the correct metering of fuel and air.

If you look at the throttle linkage on the driver's side of the carb you will see that it should rest on a screw at idle. Turn that screw in a little should solve your problem.
If that doesn't fix it then you will have to adjust the mixture screws in front.

Well the choke has an electric part that heats up and makes the choke open in a few minutes. As soon as the engine starts the choke should open about 25 percent by way of a vac pull-off.
You can take the air cleaner off and watch the choke while someone starts the engine cold. If the choke does not open after it starts, check the choke pull-off. You can also open the choke with a screwdriver to see if the engine clears up.

Is it hard to start? The choke has some notches on the side by the electric choke plug...rich to lean...If hard to start cold, loosen choke screws on side and turn the dial toward close (rich) retighten adjustment screws and recheck performance...If choke stays on to long after warm up (idles fast) adjust the choke toward open or lean position. Try no more than 2 notches either way between tests...Hope this helps.

Believe it or not I used to be a mechanic for chrysler. There are a couple of things to look at and I'm sure you'll find the problem. #1 is to check for any vaccuum leaks in the hoses and the intake manifold.I do this by spraying carb cleaner in little spurts towards a specific area and listen to see if the engine rpm raises while it is running. #2 is a carb problem--Usually with the high idle solenoid (located on the Passenger side of the carb) or the choke. Check to see if you have power at the wires leading to the using a test light or a volt meter before you start it up. If you do have power then start the vehicle or have someone start it for you while you are under the hood and examine the choke operation. B4 you start it the vehicles choke should be completely closed. If it is, it should open as the vehicle warms up when working properly. If not working properly it will either stay closed and cause the vehicle to flood out or run rough and backfire or it will be open(stay open ) and the vehicle will not stay running unless warmed up for sure.# 3 It could also be caused by a combination of the high idle solenoid holding the choke open and then causing the choke to stick open.

I don't know the year model, if older carb, sounds like stuck choke, bad choke pull off or bad needle and seat in carb. If newer model, computer staying in closed loop, bad temperature sensor.

it seems that your coolant temp senor is what causing this to happen it's natural inless it revs really high and stays above 1100 rpm's after the engine heats up.

hi how are you. your auto choke is bad will need to replace.depending on wich one you have it may only be the vacume choke diafram ( high idle cut off). or it is the electric choke

Sounds like your choke is sticking.Try to make your choke stay open with something after the engine is warm and see how it runs then.If it solves it you may need a new choke or get it adjusted.
