Preferred carburetor for mild 360?

Here's a video I took yesterday of the idle, showing tach and vacuum gauge... this was how it was idling without me touching the throttle... this was with the timing marker showing about 30 degrees of advance (all vac lines disconnected and plugged)...

Today, I took the carb to a carb shop to see about having them rebuild it... they took a look at it and convinced me it didn't need to be rebuilt, that the eddy carbs hardly ever have vacuum leaks anywhere except at the base plate.. they did agree that it sounded like the carb was running too lean, so I bought some thinner metering rods to richen it up a bit. Gonna give that a whirl tomorrow and see if it helps. I've got someone else sending me a new harmonic balancer, since it sounds like mine has slipped and is not accurate....

I have double and tripled checked my firing order.. it's ok. I'm gonna go out and pull a plug or two to see how they look from the way it was running yesterday and this morning... and I'll see how they look after changing the metering rods tomorrow.
