258 carb

My brother just got his 82 or 83 CJ7 running again. He wants/needs to replace the carb and perhaps the intake. He needs some ideas that will be smog legal(Idaho). A search on this board revealed that the Weber is the carb of choice. Is it smog legal?

Any help would be great.

Thanks
Scott

Re: 258 carb

It is my understanding that the Weber is sold for "off road use" only. I've had one for over 2 years, great carb, but most likely will not pass if you have visual inspection.

Re: 258 carb

Brad's correct. The Weber will fail the visual emmissions tests if you have one. I don't. Mine did pass the Delaware tailpipe test when I lived there

Re: 258 carb

I believe the Weber 32/36 is legal while the 38 isn't. I've got the 38, since it produces more HP (but less torque) and I used to play in the mud where that was required. It really needs a cam to make the 38 work...

Re: 258 carb

Neither is legal in most states, this is due to the adjustable mixture screws, factory carbs that fell under emissions standards usually had the air screw covered or sealed. Pretty stupid IMO, but leave it to the feds.

Re: 258 carb

I dont know much about other states, but here it seems that most inspectors would not know what they are looking at when it comes to older jeeps and what was stock and what was not. I work at MEPCO 4x4 and we sell the Weber carbs all day long for the 258s and I have had only one person come back and say they could not get it through inspection and it was because it was failing the sniffer test and not the visual inspection. It turns out the people installing it must have been idiots, because after I told them were to take it to have it tuned, they never returned. They will pass the sniffer tests without trouble IF they are tuned right. That is the key especially for high altitude areas. They come calibrated for sea level and must be re-jetted to work at the higher altitudes. If you do that you should not have a problem. Good Luck.

Re: 258 carb

Thanks for everyones input. My brother bolted on a weber right out of the box and has been driving it. He told me that he has not even fine tuned it yet and it didn't need any adjustments at all to make the engine idle very smooth.

Re: 258 carb

how does the webber do on extreme angles? is there a way to make the bbd work well in off-camber situations? i've lowered my floats a bit, and bypassed the "computer", but she still coughs a bit on the steeps

Re: 258 carb

I also had the same problem, at extreme angles, it would cough, sputter, run rich. Lowering the floats worked for me, but alot of people report that a small fuel pressure regulator set to maybe 2 or 3 works well, too. Do a search here, it was covered in depth not to long ago

Re: 258 carb

I guess what is officially legal depends on your state. Massachusetts doesn't have a visual, but my weber has passed the tailpipe test for about 3 years now, and that was with full mechanical fuel pump pressure, and no adjustments out of the box, other than idle mixture. I just put the adj. fuel pressure regulator on it, because everyone here said it helps on inclines. I've been very happy with the weber, and it takes quite an incline to make it cough. ...but, there's always a bigger incline. [img]/wwwthreads_images/icons/smile.gif[/img]

I have to put the Jeep on the dynomometer emissions test this year come November, so that ought to be interesting. [img]/wwwthreads_images/icons/crazy.gif[/img][img]/wwwthreads_images/icons/tongue.gif[/img]

Good luck
