Q jet choke has defected

That's a neat gizmo @Georgeb. A little outside of my fan skill set though. So did you have a manual pull knob inside the cab?

First thing I would do is get a flat head screw driver and a shop vac and clean that mess up on top of your engine! Holy freaks I can barely see your engine let alone anything else!

Ya unless you can get that screw out, your looking at either a newer carb with electric choke or a new intake so you can remount the choke spring properly.

Yes, I had the pull knob inside the cab mounted through a little bracket below the dash. I would put the pedel to the floor, pull it all the way, pump it one more time and start it. Then push it in about half way and let it warm up a bit. It took a little to get used to but prior to getting my 78 C10 with the same setup you have all I ever has was a manual choke pull.

Heck that sounds like a better system anyway. I tried a better drill bit this morning, and I actually got some metal shavings out. But I didn't have much time to fiddle with it. Got my 04 sold today so I can focus on getting this truck in better shape. @MadOgre a clean motor is no fun to work on though.

Finally got this fixed. I got a higher power drill and a good bit set and finally have a choke again after 10+ years. Now if anyone can tell me how to adjust the secondaries properly I'd appreciate it.

Good deal. Glad you got that done.
The secondaries open by demand from the engine. The pull off keeps them from flopping open too quickly and causing a bog.

This should be a link to my adjustment sheet.

Thank you for that link, I'll see if I can get some time to mess with it this week. I'm scared to do too much to it, the truck runs great and gets decent mileage all things considered, the secondaries just aren't working as far as I can tell. I def don't want to end up with it running poorly.
