i have a newly rebuilt 261 and a rebuilt rochester carb, i have it running good except that when cold and i pull out the choke it will rev up a lil then it starts to load up and miss, i know that it will load up if the choke is kept on but i push the choke in a lil and the rev comes down, i would like it to be like my old 235 that would rev up nice when choke is on and slightly push in the choke to drive...

something is not right and is bugging me, also there is to much vacumn on my vac advance at idle, i had to lossing the vac line a tad that way i created a leak so that the vac advance would not b ingaging at idle...

please help
