help with a 68 c-10

A kit is good if you have a complete but gummed up carb. Since you are missing pieces, I'd do like others have said and buy a reman job.

Now for some fun.
To find your fume leak.
1. Dissasemble entire cab.
2. Media blast cab removing all paint and caulking.
3. Re-caulk as outlined in the Assembly Manual
4. Repaint cab
5. Replace all grommets on the firewall.
6. Reassemble entire cab.
Try to be done by dinner time.

Seriously if you want to find a fume leak, inspect all the small openings in the firewall from inside your cab. Put a shop light under the truck and another in the engine compartment. You should see several places where exhaust could get in. I use dum-dum (a sticky, greasy putty) to temporarily fill small holes. Bodyshop guys will have this on hand to use as window putty.

Lots of us have enough rust that we'll never fill all the holes.
