okay so i have a q-jet for my 305 v8 and it uses a coil choke. my main problem is it seems that my choke pull off isnt opening my choke blade when im turning on my car. what i have to do to get it to run is floor the gas pedal and if i let it go the car dies. so could this be a faulty choke pull off? because apperantly the linkage inbetween the pull off and the blade is moving just not enough to open the blades up. could this cause the reason for my car being a pain to start? if so why? this is a brand new "rebuilt" carb i just bought from a parts store can the choke pull off allready fail me?

88 should have an electric choke, if so, verify that the connector on the choke thermostat is good and the contacts on it are clean

the engine was aftermarket the car came originally with a v6 and was fuelinjected but now its a rebuilt 305 v8 from early 80's late 70's and the choke isnt electrical

trust me

Do you see the phillips head screw on top of the arm that sticks out the back of that vacuum diaphragm? That's the adjustment screw for how far the pull-off open the choke plate immediately after startup.

Obviously, it would be a good idea to make sure the vacuum diaphram is in functioning condition before playing with the adjustment screw. Make sure it holds vacuum and retracts/extends easily. It should pull firmly to the fully-retracted position as soon as the engine starts and stay there.
