ha ha, get used to it. turn it in till it stops,, but not too hard like shee4speed said. 1.5 turns is a good starting point when you get jetted, but adjust them till it idles the highest when warmmed up. if you have to go much more than 1/2 turn either way, you'll have to move the needle. when you say 500-3000ft, is that riddin up a mountain, or several different spots to ride? if it's the later, you should adjust for any major altitude changes, because, that big of a difference, would make it not want to idle. ie. if you adjust for 500, and ride 3000, it'l load up with fuel at idle. the opposite, it will be a bitch to start and might stall, so keep a small screwdriver with you, or just don't ever let it idle lol. <---j/k oh yah, it might help to trim your lids and throw them on for the lower elevations
