adjust your carb, the 2 screws on each side of the carb adjust so you can get the car to idle correctly, also check your distributor

When you say it's destroying the air filter---do you mean it's all sooted up ?? I am assuming that what you mean.
Try disconnecting the vacuum line at the egr valve and see if that helps.
But it sounds more like a plugged up exhaust system.Try disconnecting or looosing the flange before the cataylic convertor and then see how it runs.

SOURCE: just rebuilt carb(rochester quadrajet

Rebuild the carburetor,and make sure the ports are all clear,small,and large,make sure the float is level,and there are two plugs in the bottom of the carburetor,that are about the size of a pencil eraser,use jb weld,and spread over the plugs.They are bad to leak fuel into the intake,these are on the bottom.The jb weld will seal them up.

Choke ligt on at idle 1986 chevy w/ quadrajet carb


sounds like the float is sticking or may have a hole in it, you can try adding some automatic transmission fluid to the gas - sometimes works if it sticking,check for a vaccume leak - but usually won't overfuel with a leak- but has happend.

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

Why is my 350 chevy engine misfiring


What year and is it the factory engine? If it is carborated the choke may not be opening enough and is starving it for air and running rich. What spark plugs are you running? Have you replaced the vacume hoses and gone over the engine tightening(torquing) intake, carb and other parts?

1987 threequrter ton chevy 350 moter with quadura jet carb running rich an smokeing


either the float is sticking, when it is running use the back of a screwdriver and rap the bowl and see if this helps, or the jets need adjusted, start with the right one first, turn in untill the motor starts to lag then open it up untill the rpm stops climbing, do the same with the left one also, see if this helps. let me know.

1981 chevy pickup with a carburated 305 is hard starting, runs rough and when warmed up runs fine.......have replaced two carbs and the problem still exists......the carb im using now is a factory rebuilt...


Is the choke operating properly? You say the current carb has an electric choke, so I am assuming the original carb did not have an electric choke. If that's the case, have you wired the electric choke to a power supply?

I have a motorhome make Honey 421S with a chevy 454. the choke light stays on, and it smells like a gas station after a ride. Consumes lots of fuel and I don't understand the vacuum system. Anyone can...


Update? If the Motorhome has a carburetor, its pretty old and has a P30 chassis. Gm makes the truck, Honey makes the camper. Check the electric choke and make sure it has power to it when the engine is running, if not check all fuses. I dont have a diagram to see where the choke gets power from. Make sure the choke pull off is working, its a little vac can on the right side of the carb, if it leaks, it wont pull the choke flap open. Anyone that works on Quadrajet Carbs can fix it for you.

Your automatic choke is probably sticking. Spray it out with 2+2 Carb and Choke Cleaner. Do this when the car is cold so you don't start a fire. While the car is running see what position the choke butterfly is in when the engine is hot. If it is partially closed you may have a bad spring in the choke mechanism or it may need an adjustment.
