To Motorcraft 2100 or Weber??

I have heard stories about both the weber 34/34 and the motorcraft 2100. I just rebuilt my 258, put 500 miles on it and my carb took a crap, so I am looking for the better upgrade! I have heard that the weber is REALLY hard to tune and the motorcraft is real simple. The problem is that most people I have talked to have used the weber and no one seems to be using the motorcraft. I am looking for input as soon as possible, cause I have to get this thing up and running this weekend, its been down for 3 weeks! Thanks everyone!

Chris

crikifur,
I just upgraded to the MC2100 I bought from a guy on ebay. The instructions are great the install was easy and my jeep runs like a scalded ape now fantastic! It has only been a week so we will see. I bought a rebuilt carter from advance auto it ran fine but was crap on hills and ran real rich. I was able to return the carter they had a 1 yr warranty and bought MC2100 from the fellah on ebay for $285+$17 for shipping. Hope this helps

The MC2100 is what I switched to. The carb runs great now that I switched to 40's in the Carb. It ran too rich with the 44's it had. Not hard to do. The only real problem I am having is with the HEI I put on. Can't say it is not worth having, just not working for me.

I was looking at the MC2100 kit on ebay as well and he claims to have sold A LOT of the kits!!! I was hoping that I might be lucky enough to find someone who has used both and can explain the real differences!

I actually ended up putting on the weber. Still tuning out the small problems, but it was easy and is real powerful!

congrats! Doesn't really matter which you went to as long as you got rid of the Carter POS
