I just bought a 65 Mustang convertible, that had been sitting for 10 years. 74K miles, automatic. The gas tank was shot and the fuel line , so I replaced them both. Then I did the plugs and wires. Then I took the 2 barrel apart and cleaned the junk out, and Changed the inline filter. Then I got brave and tried to start it...much to my delight it did start..but ran poorly. So I went back to the carb and found more crap in it..Started it again and it definitely runs better, but still not right. Under load it seems to struggle..still a fuel problem?
Should I replace the fuel pump?
Any ideas would be appreciated..thanks
