I am using 92 Oct, we have not lower gasoline in Denmark. I am mixing 50 : 1 acc. to the manual. should I go for 40 : 1 ?
The engine runs great sometimes, but after 3 take off/ landings, start running not so good. Need more adjustments, last time it was not running well at high speed. Plug gap? Leaned the H needle was not enough. Engine sounds erratic at high speed. Dont know how to sove it.
