Default Re: Newbie questions for upgrading

At 4200 feet above sea level leaning out the carb would help.. You can get smaller jets for the carb or you can get some small drill bits and solder your main jet shut and re drill it to match your altitude. I've heard a #64 jet would be a good starting point and tune up or down from there.
