Hey all,

I have an '85' K20 Suburban. It is not computer controlled. I recently rebuilt the engine and have the vehicle running. It runs well but after driving for a while (at operating temp) it idles rough (kinda like it is missing on one cyl.). Does not do it when its cold. Any ideas as to what the problem could be. Can carburator adjustment cause this? I haven't rebuilt the carb or mad any adjustments prior to engine rebuid. Please advise.

Thanks,

Shaun
