GA8 is very much what i said, im not being sarcastic or trolling put the throttle forward and leave it there. lean to suit in the climb, once at cruise alt and speed bring RPM back to 2400 and lean to suit (i get around 55 at 7000+ feet) For the descent, dont touch the power till you start getting close, no need to baby it down, its not a io520. For starting, if cold climate (sub 5 deg C) 4 seconds on primer, if warm climate but cold engine a tad less and it will start happy as. for wam/hot starts. prime for no more than 1 second and it will go after 3 or 4 turns. Biggest thing for the GA8 is balance. it takes two 86kg adults in the back row to perfectly balance a single 86kg pilot (2 blade prop)
