Loading my YJ up and trailering it about 6 hours to visit my brother in the smoky mountains to go wheelin with him and his TJ Here is my set up: 88 YJ 4.2l auto transmission Has 32/36 weber carb and has been nuttered. No catalytic converter 4" lift with 32" tires Now, here is my question. I live at a very low elevation relatively speaking. I will be going to a very high elevation to the mountain tops. Will I need to re-jet this carb or adjust my timing for higher elevation or will it run well enough?

When I had a weber 32/36 on my toyota, I would advance the timing by about 2* for every 3-4 thousand feet, adjust the mixture screws with a vacuum gauge when I got to my location to save on fuel, and increase the idle a little bit

Thanks, I'm pretty inexperienced with carbs. How do you adjust the mixture screws with a vacuum gauge?

For the Smokies, I doubt you will have to re-jet, they just aren't very tall...most are in the 3000 ft range, if that.

I drove my carb'd jeep (MC2100) up from Florida (sea level) to Boone, NC (3300 ft)...and it ran fine.

I agree, no adjustment needed. I drove my jeep from sea level to well over 6,000 ft with only a slight loss in power.

Well shoot, I thought you were talking a 7500ft plus elevation change like I'm used to, you should be completely fine without adjustment

Awesome, you can tell I live in the 350' above sea level. I'm just a low life. Hahaha. Thanks for all the replies. I'm not gonna worry about it then.
