Use the air and gas flow adjustments on the side of the carburator to adjust the rich/lean flow of gas. there is a srew on each side of the carb to adjust one is for air the other for fuel. the one on the driversside is for the fuel and the one on the passenger side is for air. you have to turn them slowly til you get the desired results

Just installed a rebuilt carb. on a 1984 Dodge ram D-150, when coming to a stop it lopes and sometimes stalls, also when turning left it stutters and sometimes dies, worse when its been ran for a while.


You probably need to adjust the air/fuel mixture screws. Sounds like its running a little too rich. When you first start the engine, is the idle speed real low? If it is, then this is more evidence that its running rich

Rough Idle, Running rich.


Sounds like your automatic choke is giving you problems. Check to make sure the choke is operating correctly. If it ins not backing off as the engine gets to operating temp it will cause a rich condition and excessive black smoke out the tailpipe and extremely poor fuel mileage.

Fuel /emmision


If it ran extremely rich for months and now it won't start, the spark plugs are fouled out. Replacing them will fix your problem -- temporarily.

You'll probably want to check the O2 sensor(s) and replace them as they are probably the cause of the car running extremely rich.
