Not knowing where its at now, timing and carb adjustments may help a bit. However if there is any overlap on the cam, this is where you're going to get a large amount of fuel smell. Only way to tune that out is a new cam with grocery getter specs.
WRONG
I've built, tuned and driven many hot street motors that didn't stink like
raw unburnt fuel when idling
the stink is the unburnt fuel getting into the exhaust unburnt
Lean it down and add some timing until you get it the ay you want it
EDIT, make sure the cam is installed properly and not retarded a bunch
