Well, I broke down and bought a rebuild kit, pretty straight forward i guess. The three screws for the top were about worthless though, I broke one and twisted another. I had to use the old ones, I think they had a few turns left in them. I am going to be installing a manual choke but I would like to restart with the automatic one until the weekend. I am pretty sure I got it all cleaned(with carb cleaner) and put all back together correctly however I did not know about how to adjust anything inside, so its up in the air. How do I get the carb bowl filled again? Will I need to pump the pedal or what, I dont want to crank it with no gas in there right? Also, how open should the choke plate be when the engine is cold? And should it be sitting on the fast idle screw step?

Thanks as always

Re: carter rebuild, any suggestions before restart

your first adjustment would be the float level...your rebuild kit should have come with a little paper/plastic ruler, and instructions on what the level should be set at...when doing this, don't measure right at the edge of the bowl - the fuel tends to creep up just like water in a glass...i'm not sure how the carter is for doing this adjustment with the bowl cover off, but you should get it somewhat close before you install the carb...

to fill the bowl, you got it - give it a pump or two of the pedal, and turn it like normal...it may take a bit longer to start the first time, but it will go (though being a carter, you never know
)

when the engine is cold and you step on the pedal the first time, the choke plate should be closed completely, and the fast idle cam should engage (if it's cold in your driveway and you open the hood, the fast idle will NOT be engaged - it does this when you step on the pedal)...as soon as it starts, the choke plate will open just a little bit - i'm not sure on the carter, but follow the rebuild instructions for setting this (the kit for my 2100 had me set it with i think a 3/8 drill bit)...i don't think it matters greatly if it's a bit off - the BBD isn't exactly a piece of precision engineering...

also, while you've got it off and apart, have you seen this?

Re: carter rebuild, any suggestions before restart

thanks for the info....I did not do any adjustments on the float level, not really that sure about it. I may see if it is working good before trying that. It is all together, I am going to put it into Jeepo tw morning, and hope. I have gotten pretty good at settting the idle and mixture screws due to practice. There was a lot of sludge in the carb and I hope cleaning that out and replacing the seals will fix it at least for a few months. Thanks for your response!!!

Re: carter rebuild, any suggestions before restart

Just out of curiousity.... underneath the carb vent lid, this would be the one held down by three small screws, did you have a little trap door that opened and closed the side vent outlet?

Re: carter rebuild, any suggestions before restart

yeah I did, however I had earlier removed the vaccum line going from it. My friend, a Jeep mechanic did it and it now holds itself closed with the spring on it, it does nothing now. It was a part of the emmisions stuff he removed.

Re: carter rebuild, any suggestions before restart

if it was the one under the little triangular plastic piece on top, that line goes to the charcoal cannister - it's the bowl vent...not sure how your bowl is venting now if it's held closed and doing nothing, and i'm not sure what effect this will have on the behaviour of the carb...

Re: carter rebuild, any suggestions before restart

My rebuild kit came with a new round rubber vent cap that is suppose to go onto a hinged pivoting vent/gate. This vent opens when the pump arm is up and closes when the pump arm is down. My vent assembly was missing. I bought a reman carb that never ran right. Besides being virtually thrown together without any adjustments to specs.... It was missing this vent, which kind of alarmed me as well as pissed me off. Anyway... I ended up making the vent assembly to hold the supplied rubber cap/vent. I made it out of stuff I had around the house and some solder. I'll see if I can find a pic of it so you can get a laugh at my not so handywork.

That last pic was of the carb before I got my meathooks on it... without the vent... and this one should be with...

sorry it's kinda blurry.... it does hide it's ugliness... but I'ts very functional and tested with a vacuum pump.

Re: carter rebuild, any suggestions before restart

Well, I put the rebuilt carb back on, double checked everything and then began cranking. Alas, after about 10 seconds Jeepo started and idled beautifully. I almost fell down! But after about 30 seconds, fuel started coming up out of that top thing, not good I thought so I shut it down. I thought it must be the float adjustment so I tore back into it and bent it a little. I put it all back together and it started and ran great again, but after about 5 minutes, (I was watching it warm up and checking the operation of the auto choke) it stalled out and the only way I could get it to start and stay running was but holding the throttle open, keeping the RPMs at about 2k. I have the mixture screws out about 2 1/2 turns which is where they worked best before the rebuild. I did clean the idle tubes obviously while cleaning everything else, my only thoughts are that once its warmed up, somethings messing up....any suggestions please? It does have plently of gas in the tank too.

this makes it sound like your fast idle cam isn't operating properly...double check that once the choke has cooled off and recoiled itself...they can be tricky to set sometimes...also, make sure the choke isn't coming off too fast...

Re: carter rebuild, any suggestions before restart

Use the "scientific" method and use a ruler to set the float to specs. "Bending it a little" ain't gonna cut it unless you have plenty of time to repeat until it's right.

Also, you did change the fuel filter *before* you fired it up, right? My brother fought that back and forth...clean out carb, pull more junk from tank/filter, clean out carb...until he finally put a new filter on.

Re: carter rebuild, any suggestions before restart

yeah I did change the fuel filter, although it does have another one inline before the fuel pump. I will change that. How do you set the float level....I think that must be the problem, I can get to that without too much effort, I just dont know how to set it and keep it from sticking like I have read on here. Any suggestions thanks

Re: carter rebuild, any suggestions before restart

ok, I opened the carb again and adjusted the float level as per the instructions in the rebuild kit, I also set the choke plate clearance and other adjustments I believe just as the instructions asked. Jeepo started right off and idled great. I quickly adjusted the cold idle screw to about 1500 rpms. It seemed to be running fine for a while. It then began stalling and I could not get a difinitive answer as to why by moving the choke plate. I am going to wait until it cools down completely before messing with it again. I know it will always be tempormental until it is warmed up, I just dont understand why it runs great until it starts to warm up. Maybe Im not suppossed to know?

Re: carter rebuild, any suggestions before restart

The first time I had a "proffesional" carb man rebuild my carb. He damaged the floats and they filled with gasoline... soon, and I mean very soon, after they filled up they failed to float, once they failed to float, the gas just wanted to come in and join the party.... and the gas kept comin.... and the gas kept comin and comin... soon all the gas filled up their home and decided to overflow to the next home.... which was my exhaust manifold.... I extinguished the party. Check your float. They slightest mishandling can cause an unseen pinhole and lead to a very frightening experience.
