If you have a good synthetic oil in the mix 50:1 is O.K., but not ideal for break in. I would shoot for around 32:1 for break in and then go to 50:1 with synthetic.

You shouldn't have to adjust your carb for the altitude if it is running O.K. now. Have a look at the plug- it should be brown or slightly black, not grey or white.
