de-smogging a CJ-7

Has anybody de-smogged a CJ-7. I have an 81 6-cyl that I do not need emissions test on anymore. It will mainly be used for off-roading. It has the smog pump and all the hoses going every which way. Probably most are not even needed anymore and I doubt the smog pump is doing much good. Is there a procedure to follow or do you just remove smog pump and plug the hoses as needed?

Re: de-smogging a CJ-7

To give you some food for thought I can tell you what I did to my '84 CJ7 258 (which was in excellent mechanical and physical shape). My complaints started with carb problems (Carter) and the inability via computer to successfully correct things on my own. Things started slowly and progressed to where I am today.

Replaced Carter with Weber 32/36
Removed computer and all subsequent wiring
TFI upgrade
Cat converter removal - replaced with pipe and Flowmaster
Removed pulse-air system
Charcoal canister removal (kept until recently - went bad)

The setup now is pretty simple-

Capped all unused vacuum ports/lines
I have one vacuum line from carb (ported) to the distributor
I have valve cover PCV to manifold vacuum
Oil breather on rear of valve cover
Fuel vent line capped with large, clear fuel filter (I could probably cap this off and run a vented gas cap instead)
Fuel pressure regulator to carb (via filter)
Utilize the Oxygen sensor to run Air/fuel gauge

This is working well for me and has really cleaned things up under the hood. I've also kept every single item that has been removed from my CJ just in case . . .

Re: de-smogging a CJ-7

I got rid of my smog stuff after an accident. I took off the air pump and plugged all the lines, including the holes in the exhaust manifold. It runs better. We could get a lecture from the greeenies, but I think if you keep it running better, it pollutes less. I have no wires going to my 81's carb including the choke. I kept the charcoal canister. I don't think it does much, or hurts much.
