    I have a stock 305 on my 85 jimmy with a stock carb. I just rebuilt the carb but I am still having problems with the choke not kicking on and I also have problems on colder days when the carb is sucking in way too much gas the truck is bellowing out the back with black smoke. Now I need to know what to do and how to fix these problems. Any help would be appreciated as winter is setting in.

    Where does the auto choke wire go to after it leaves the heating coil? Is it the blue wire that connects to a plastictube by the starter?


    Thanks

    you'll need to start poking around with a tester to see whats up. I think there is a sensor that gives the choke juice after its started, other wise there would be no point in having the choke pull off before its started. See if its getting power first and we'll work from there.

    Well your choke could be out of adjustment or more likely, its junk. They're really easy to change, just a few screws. Once its on you can adjust by turning the big thingy in the middle to set it for lean or rich.

    More importantly right at this moment I need to find out where the wire goes from after it leaves the choke coil?
