I just got done installing a Motorcraft 2150 carburetor on my 89 why Jay. After coasting in gear and re applying a little Excella racin I get a slight hesitation and sometimes it bucks a little. I noticed that if I take my vacuum off of my distributor it runs a little bit better. I believe this is a ported vacuum line. I feel like the fuel supplies adequate and leaned out. Any ideas to stop the hesitation or bucking? Much appreciated. Peace out wranglers
