I have found there is a small lock out that can be "bent" out of the way. But why someone would you want to use the back barrels before the engine is warmed up sounds foolish to me.
Also, if it is an electric choke, there is a vacuum pot called "choke pull off" that can go bad and the choke will not turn off. Again, not sure if Chevys use it but it caused all kinds of hell when it went bad on my Catalina.

Well, that all makes sense. I have a lot to learn about Qjets but I'll get there. I guess I should start with the s# and see if I can find out if it is even the original one. Some say it matters and some say it don't. Not that I am trying to keep it original, this is a plow truck and I need it to be reliable more than anything else.
