That's close!!
You don't adjust the rotor exactly. You rotate the distributor body clockwise for more advance, counterclockwise for less advance.
8* might be stock but you should be able to advance that up closer to 12 to 14. I live at the same elevation and weather as you do and run all my stuff at 14 initial. Block off the vacuum to the vac pot on the distributor when you check and set timing. Also increased initial timing will likely increase your idle slightly. Just turn the idle back down on the carb if needed.
Here's a link with some good info on timing.

I did mention adjusting your apt but get your timing good first and then we'll decide if tearing the carb down for some mods is worthwile.

Could you also post a pick of your engine bay.
