Yamaha 55 tune up specs.

Can any body assist me with the correct tune up specifications for a YAMAHA 55 EL that will be run at 6000 ft above sea level, and what sparg plugs should I be using ( NGK SPARK PLUGS). I use a 50:1 fuel oil mixture, then fuel available is about 94 octane unleaded, <br />thank you kind regards WILLIAM Wright.
