Carter bbl

I'm having starting issues on my 89 wrangler 4.2l Amc 256 l6 with a carter bbl carb with an electric choke if I would convert the electric chock to a Manuel one would I be able to start my jeep easier.
It doesn't matter if it is 85 degrees or even 34 degrees it still takes 6 times to start the carb has been rebuilt 2 mounts ago
Thanks

I just did this on mine, but for a different reason. My choke was actually not disengaging all the way on its own so after it warmed up, it ran like crap. I could have fixed it but I kind of like manual controls The manual choke does have a bit of a learning curve if you've never used one. It takes a little bit to figure out exactly what makes the engine happy. It will only make stating easier if there is something wrong with your automatic choke. There could be other problems that cause hard starts. For instance my timing chain was shot and when I replaced it I had no more hard starting problems. You can take off the air cleaner assembly and check the choke. Its the big flap at the top of the carb. (if you don't already know that). When the engine is completely cold it should be closed. When you first start the engine, there is a vacuum pull-off that will open the choke slightly (about a 1/4 of the way or so) as soon as the engine starts. As the engine warms up the flap should open all the way. If it doesn't do one of these functions properly than you have a problem. I left my vacuum pull-off connected with the manual choke so it still does that function on its own when I start it. Hard starts would be caused by the vacuume pull-off not working, the choke not closing all the way when its cold(the engine not outside temp.) or being stuck open. Hope this helps

You probably just need a new choke coil, they are a maintenance item and do not last forever.

It is the bi-metal spring coil that closes or opens your choke blade depending on temperature.

The electric portion of the choke DOES NOT aid in starting, it aids in disengaging the choke once the engine is running. These are not outboard engines, the term "electric choke" means something entirely different.

If you are having trouble starting, get a factory service manual and set the carb and choke to specs. Check that your fuel filter is installed such that the bypass fitting in the 12 o'clock position. Make sure the check valve in your fuel pump is not leaking. If your carb leaks down, or the fuel evaporates out, you need to fill the float bowl up before the engine will fire. Takes 5 to 15 seconds of cranking to do this, totally normal for a carburetor.

You should read up on the laws in your area for passing emission inspection. As far as I know, its not legal to change your carb for another in Cali

Fill out your profile.
make your own thread. Your problem is different.
Your carb is not a nightmare, it is a mechanical part that requires maintenance after 20 years of service.
