Ok I got the motorcraft 2100 and sh*t canned the Webber <img src="/forums/images/graemlins/kewl.gif" alt="" /> but I got one with 1.14 instead of 1.08 so I am still pushing 300 cfm and its a smog less carb so I lost my vacuum advance so I just advanced the timing a bit to about 8-10 btdc but when i put a load on the motor it wants to bogg down a bit triple checked for vacuum leaks and found none there is a spot on the passenger side of the carb towards the front bottom of the barrel for a vacuum port and I am looking towards hooking up to the advance there, I am positive I have it tuned right its pulling about 20" vac and has great throttle responce when you snap the throttle but wants to fall on its face when I get on it slow what do you guys think hook up the advance or too much cfm?? any other thoughts would help too thanks <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
