There could be all kinds of reasons your vehicle runs rich. It should be fuel injected not carborated. It could have a bad injector, bad air filter, o2 sensors etc. Have it scaned for the reason.

Carb adjustment 1994 GMC throttle body carburetor


A 1994 model should have throttle body injection, not a carb.
There's nothing to adjust for fuel mixture. That is controlled by the engine computer based on 5 or 6 inputs.
The problem could be one of the injectors, or something else.

How to tune a b210 caburatorI manage get the idle tuning perfect next how to tune the rune up(when in running it put out blak smoke)


Something internal in the carburetor is wrong, maybe the accelerator pump seal or gasket is bad. Think you will have to put a rebuild kit in the carb. There's no outside adjustment for it being way too rich.

My 1986 GMC Vandura With a 305 and rochester Q Jet Idles Rich and after it warms up looses power and floods out stalling where ever it feels like. Please Help,


Possibly a hole in the float . ( carburator) You'll have to take the carb apart and remove the float. Shake it and see if there is gas in it. If it's not a brass float, you may just need to adjust it, and clean the carb.

1979 sierra grande runs too righ even after adjusting carb


You may have an internal carb gasket leak or your floats may be adjusted too high.After you run the truck look into the carb to see if there is gas still dripping into the carb bore.Also after running with engine on remove the front fuel level check screw. (have lots of rags under to catch fuel) Fuel level should be right below hole.If it is spilling out it is too high.Floats need to be adjusted up for fuel level to go down.

My 83 cutlass supreme check engine light on


It means the car is running too rich. Check the air filter. If it clean you will likely need to rebuild the carb if it hasn't been done. If it has you might just need a carb adjustment.

I have a 1981 GMCvandura 25 with a 350 4bbl carb. the choke.


Its all in the idle screws, if there bad you will be chasing them every time you drive it, also the choke spring inside could be bad, if you have a that style. screw the idle in on both sides all the way in, then back out 2 and a half turns, this should be where you will run the best. adjust as needed, but that is the standard. i also run sea foam through the carb, alot better then any cleaner on the market. usr it in your fuel or try to put it in the carb, i have uesd the vacume lines to do this, but you will also have to keep the car at high idle when doing this, it will clean all of the junk and carbon out of the entire motor.

if you need more help, please be clear or the carb, and hat you have done and not done already'

thanks
