Re: Carb Question

I'm affraid you have no choices. I did some research some time ago and the only options I could find were illegal.

Re: Carb Question

I put the Weber replacement carb on my 1989 YJ 4.2 and never could get the thing to idle. To me, the motor ran better before I made the change except that it did have more high RPM power. Weber was no help. I even had to ship the carb back to them because the butterfly valve got stuck in the closed position. The tech told me on the phone that all he did was give a good rap with a hammer. (I could have done that and saved $20 on shipping.) It was $370 down the drain.

Good Luck!

Re: Carb Question

some guys put hollys and webers on but not smog legal. notice the manufacturer has a little note "check local smog laws".

i put a new rebuilt carter by holly from checker auto on my 87 and it runs great! passes smog for tampering and all the other tests they can come up with! here in tucson they test us each year. i have 3 cars and i do different tricks to each to pass! you know the routine mr![img]/wwwthreads_images/icons/smile.gif[/img]

Re: Carb Question

The are pre-computer Carter BBD carbs. They don't have a stepper motor on them and are a bit better than the later units. You could get one of these and carefully eliminate all traces that there was once a computer in there. Or get an aftermarket two-barrell and go mudding before you take it for inspection. If they can tell its not stock through all the grime I'd be amazed (If they would even dirty their hands to lift the hood I'd be amazed!)
