83 12a, Missing at cruise speeds
 

Everthing works, acceleration is ok. But a cruise, both highway and city speeds it seems to have a miss. Aside from plugs, wires, distributor, coils, what next to check?

stock motor?

Fully stock motor. Aftermarket catalytic, fusible links changed to fuses. Stock ignitors. One stock coil, one Crane coil. Thats its

Carb rebuild? Sounds like dirty air bleeds, tubes, or jets. BTW this is the builds thread. Youd be better off posting in the technical section.

Oops! will move the post.
