On side of the carb is the idle adjustment screw. As far as the choke that shouldn't need adjustment if it's hooked up properly. Start by taking off the air cleaner to provide good access, now with the engine cold, move the throttle at the carburetor lever all the way to full open, or full throttle. You should see a flapper valve close over the top of the carburetor, this is the choke plate, does it close? Hope this information helps you. If you still have questions let me know. Also to confirm what engine is in the vehicle? I am assuming the 6 cyl.
Thank you,
Lee

    lee, Thanks for info but when you say idle adjustment screw there are 3 screws one looks like it's for the choke linkage then there's one next to it that just tightens on carb body then there's one that has a cylinder(vac operated) which I'm assuming is ajdustment for high idle? Do you have to tune all to work together. Thanks again, DON

    Sorry, it is 6 cyl.

Dont know how to hook up carb


Hello, the best advice I can give for this is to mark your old vacuum lines off the careburator and match them with your new one. A good Chiltons or Haynes Auto Manual can help you in this endeavor as well. Being a mechanic doing upgrades to your vehicle does not always have the manual for the conversion in which you are doing so some good ole guess and tell may be the route to take. Just remember that you need vaccum to take and take out air into the careburator and this is a good start from any careburator upgrade. I have rebuilt and installed probaly 50 careburators and a manual for converting one careburator from one vehicle or motor can take longer than some just good time with your motor figuring out what needs to get done. Thank You

22r Carb. misses at ide


Dripping fuel could indicate a badly adjusted float,bad needle and seat,or possibly to much fuel pressure off the pump,if your using a mechanical fuel pump make sure the return line to the gas tank isn't plugged,if your usining an electric fuel pump make sure you have a working pressure regulator,my personal opinion on remanufactred stock carbs isn't very high,if you can return the carb I would highly reccomend replacing it with a Weber 38 DGES,you can get a Toyota conversion kit for around the same cost as a remaned stock carb.

1988 jeep wrangler carb trouble


Ok... If you have any experience with carbs, you can get a rebuild kit. The most important part of any rebuild is to clean out obstructions in the passageways. Most times this can be done by using carb cleaner and spraying compressed air through them.Most times, just spraying cleaner into carb while installed is a waste of time as debris usually consists mainly of fine rust particles from inside the fuel tank, which will remain in the fuel bowl unless physically removed. If you can't do this, next best option is to search local junkyards for a similar unit. When replacing, cut the fuel line in a convenient place ahead of the carb inlet and put an aftermarket filter in the line, to prevent debris from re-entering and causing further problems. Most carbs have the adjustments blocked off. before using, it is wise to have someone who knows how to remove those plugs, do this for you so you can adjust it after installed.
Good luck
