Idle problem on C15 261 CU IN

Maybe someone has had this problem also. I am having trouble getting the Chevy six to idle nice. It never quits but seems to go up and down about 150 rpm when idling.
I put in a carb kit (Rochester B) and added a pertronix ignition. Still not
idling nice.
The pertronix was quick to put in and the engine starts instantly now. Also the plugs had been black with poor combustion but I took it out for a spin and they
are all light brown. I think that it also has way more power than pre pertronix.

The distributor vacuum seems to work fine but this engine does not want to idle
smoothly.
