well had the old girl running great new valve....cleaned up head..new push rod...etc. etc....the guy who had it before me put a rochester carb on it....the holes on the carb and intake didnt match up so it looks like he ground out the hole on the carb to make it work......lololol.......no big deal until after about 3 nice days of driving the old girl around gas started shooting out of carb.....so i did some tinkering on it...took old carbs out of the barrel and started to replace parts....i got the truck running again ...runs nice on idle then once i take it on the road it runs rough as hell.........does anyone know of a fix or a nice replacement.....the mixture screw on this one is turned one complete turn and changing it doesnt do much....i may have to bite the bullett and pay 150 for a new one....
