I need some help picking the best carb for my 51'GMC that has a 62' chevy 235 insalled in it. I want to keep the manual choke and throttle.I'am taking a rochester "2 jet" off and it can't be rebuilt.It's not the original carb and was just plumbed to work by who ever put the 235 in it. Also, can any one steer me to some pic's on differant ways to hook up the linkage.The truck has had 10 fathers before me and they all had their own ideas and none of them good. Thanks!
