i need someone to give me an estimated guess on what size jet and position of pilot needle. i am around 500ft above sea level i'm running a 310 jet and i set my needle to 4 which i think should be way to rich but idk. i tried messing with the air screw on the side of the carb and sometimes it will start to run good at 1 1/2 turns but then it will bog at around top of 5th and 6th at high rpms so i'll change it to 1 turn and will run good but then start to act sh*tty again. i would have tried trial and error with jet sizes but all i have is a 180,230,240, and 310. so i may need to buy 280 and a 290
