Carb Winter Mode?

Hello Forum

I've looked all over and couldn't seem to find it (then again I also don't know what I'm looking for)

Is there an adjustment for winter on the stock '89 carter carb other than the choke?

I have an 89 4.2 with an original rebuilt carb. and it runs the same summer and winter except that the high idle is a bit lower in the summer due to temp. which is normal. Now that it's starting to get cold it goes right up to 1800 rpm, where I like it, before I kick it down. 2200 I found was a bit too high. I run the auto choke at the 1 rich setting and never have a problem. You can adjust the choke setting, set screws, solenoid screw, and idle set screws. As 4Jeepn said, is there a problem? If there is and you're more specific maybe we can assist a bit better. I wouldn't start touching that carb. if you're not that familiar with it.

I don't want to touch the carb even if I was familiar with it

I'm just asking cause its getting REALLY hard to start in the mornings, this morning it took 16 cranks, and that was with the choke and full gas

Check your choke setting to see where the notch is. Loosen the screws, but don't remove them, and turn the housing to the 1 rich setting. When cold, open the throttle to see if the butterfly closes. If it doesn't there is an internal problem with the carb. which could cause the hard start. Possibly the choke spring could be broken. The first thing I would do is spray everything real good in and out with Carb. cleaner. It might be just a bit gunked up. Once it starts does it idle and run o'k. If everythings working right once you pump it 3-4 times and set the choke you shouldn't have to give it gas. The reason I say pump it a few times cold is because these carbs. leak internally and it takes more gas in the bowl to get them going. You might be at the point where you need a good rebuild or upgrade. A search will tell you what other individuals have done to upgrade from the original. Mine starts and runs great so I'm leaving it alone.

I know that it leaks already, Do you think that could be the main issue?

If you're running the original carb. and you're over 80,000 yours needs to be rebuilt or consider an upgrade. I hope it's not leaking fuel onto your engine. First tighten down all of the screws and then use carb. cleaner externally while it's running. If the carb. starts to stumble then you have an external air leak. If you're leaking fuel you need to replace it anyway. I don't think that's going to cause the hard start. It's usually a choke/proper amount of fuel in the bowl problem, given that you don't have a sticking or damaged float. I guess what I'm trying to say is that if cleaning it in and out doesn't help and you can't determine if your choke is functioning properly, time for another carb. Do a forum search and consider an upgrade. I like the original set up because when they're right they're great. I know I'm in the minority on that one.

If you have not done the nutter by pass yet then you need to consider doing it.
it will improve the cold starts immensely and make for a better running motor all around.

but i would guess that your choke is not working right now and that is your issue.
take off the air cleaner and see if it is closing all the way .

This is a Picture Guide to Nutter Bypass - JeepForum.com

Heres the thing about the nutter bypass... Its Illegal, and when I get my YJ inspected they check all the nooks and crannys for things to fail me
