Running rich....To big of a carb or?

Try this, turn the initial timing up until it lugs the starter, then back off 2* and retune the carb at that point. Don't worry about total at this point, get the idle squared away. It might clean up that rich odor a lot.

I run stock 340's at 14-16. A 318 with any type of cam is likely going to want more than 16.
