Live at 3000 ft. Alberta Canada. Runs like shit below 8k rpm. Dropped needle. Opened air screw. A bit better but not great. Plug is brown. 25 to 1 mix ratio. Any thoughts. I can afford the lectron 800$ in Canada

Why 25:1 ratio? Have you ever tried 40:1?

Don't bother. Get a keihin instead or dial in the mikuni.

my 19 150 ran great at 44:1. I liked the Motorex oil as well. Look up the slide notch mod, it helped me some.
