Howell Fuel Injection and assorted problems

I have a Calif 1976 cj5 with the 258 six. It has a 1v carb. I see the howell is for the 2v carb. I guess I would have to change the intake?
I bought the jeep and all the vac line were plugged off and the smog pump did not have a the belt on it. The thing ran rough and fouled the plugs after a short time. I replaced the smog pump belt only to find the pump was siezed. Replaced the pump and hooked it up as well as the vacume lines and emmissions equipment. It started but ran bad and sounded out of time even though I did not change the timing. backfired and blew the little round thing in half that comes off by the egr . cpo? I discovered it was epoxyed together before .
So now I an replacing the timing set as it seems to have a lot of play. The gasket was leaking bad anyway. I wish I had bought a non smog jeep but only piad $1300.00 for it and it is in very original condition. Any advice would be great to this jeep newbie. Thanks

Im in the same boat with my 77 I recently bought..Now there are alot of places to look for a 2b intake manifold, but I would start with for a used one, they are good people. Remember that you need to either match it with your exhaust manifold by year, (70s, or 80s) or get a matching set of intake and exhaust and do some minor exhaust work.
I had to go through this to deal with the howell, Im just not going to mess with the smog gear, I tracked down some of it, and still missing alot, not mentioning that it gets exspensive fast, all to run like crap with all that crud on it.
I decided that I wanted to upgrade anyway, so I got the howell, and a new HEI, and gonna get wrenching this weekend.

Ill let you know how it goes. Let me know if you have any parts you are looking for smog wise, I ended up with some parts that it doesnt look like Im gonna use.

Good luck.

im not sure how California is with emissions on old vehicles. do you have antique plates and whatnot? best thing i can suggest would be to call howell, they are pretty helpful. you could also double check that all the vac lines are set up right and that nothing is clogged or leaking.

Antique plates don't mean crap in CA unless your vehicle is pre 1976 "smog exempt"
Howell is the best way to go, Even on the super basic smog components of the 76.
