I have a 1990 Jeep Wrangler 4.2 I-6 with a Weber 34 DEGC and my secondaries aren't getting enough gas they bog out when I try to take off after a red light or going up a hill. Its such a pain and I look crazy trying to get up a hill. :confused::confused::confused::confused::confused:

Does anyone have this problem?
Any info will help!!

no, its just a crap carb. its not really made by weber, just by a company that weber let make it and use their name. its a piece of junk. i had one and would rather use the carter then that 34 again. when i had to put it back on because of repairs to my normal holley, it felt like i was driving with a one barrel carb and a 4 cylinder engine.

Thw guy from colorado is great. He is a member on another jeep forum i am on and he is always helpful when it comes to mc carbs

On jeepz, his name is gronk.

I have a mc2100 from a 65 mustang with the 1.14 venturis and 47 jets. It works pretty good

Lots of people have had good luck w/ him....others had problems. Overall, he seems to take care of his customers.

OR......you can do it yourself for under 100 bucks w/ basic hand tools & decent mechanical skills. The adapter is widely available for 15 bucks, ditto w/ a 9" air cleaner. You can get those carbs off Ebay for under 50.....or your local junkyard for less, probably. Plus a rebuild kit and some good carb cleaner & you're set. The 'hardest' part is making a little strip of metal to extend the carb throttle arm so it works /w the downpull Jeep cable you already have. There are a couple of decent write ups on the process out there that a quick google should turn up.

yup. i did this /\

cost me nothing since i had the adapter already and you can use the weber parts for the accelerator adapter. gained 3mpg using the mc over the weber and holley
