Vacume routing 231 buick

I know it is a dauntless forum,, But my dauntless was replaced with a 231.. I need a vacume hose diagram. I cannot find one like mine in any of my books. It has a rodchester carb and Hei. Can't imagine it could need much.

It was backfiring through the carb and the exaust all at once and smells rich when running. Thought I should get the glob of capped hosed and open ports straightened out before I start blaming the timing.

 

if it's a 2G carb like mine the p/s front corner of the carb goes to the hei (~1/4"), the rear p/s of the carb goes to the PCV valve (~3/8"). Only other vacuum hose is tiny on the intake and goes to heater controls if you have the vacuum box

 

Thanks I will try that setup and see where we end up..
