[REFORMULATED]

Looks like it's running a bit rich to me and is not oil related. If it blows out black smoke after sitting for a while then clears out that's an indicator that the primary and or secondary bowl plugs are leaking, common problem especially after the carb's been hot tanked. It's an easy fix. If it runs rich all the time then I would check the float level first, next the ensure the primary jets are seated properly. More than likely something was not done correctly on the rebuild.

This forum can help you figure it out, cliff is a genius: http://www.cliffshighperformance.com...machinesforum/
