I have a 03 Mountain Cat 900 carb, was running lean went from a 440 to s 450 went out still running lean. I Recently went one size down on the starter jet. Would that effect my lean condition or what gives
Is your sled running lean at WOT or in the mid range? If it doing it in the mid try moving the clip on the needle down one slot. If it is at WOT it would be your mains.
