I just did the Motorcraft 2100 1.08 venturi carburator swap on my 1990 Jeep Wrangler. The Nutter bypass was performed on this jeep by myself about 3 months ago.

My question is: there is a flat spot when accelerating. It is at about 1/4 throttle. Is this normal? It idles normal and performs 200% better than the stock Carter carburator except for the flat spot. Anyone ever had this problem or know a fix for it?

On a side note, I just installed a Weber Carburator on my freinds 1990 wrangler that I just got done rebuilding after an engine fire and did the Nutter bypass. I wish I had $500 for a Weber. It is flawless.
