This is what I did, see if it makes any seese to you.....I played with both high and low needles and here's what I came up with. I opened the low end first 1/4 turn and opened/closed the high a bit and ran like trash....next I closed the low end about 2 1/2 turns and also closed the high end about 3 1/2 turns and the engine ran like a champ on the ground and also when I picked it up vertical, it idles nice about 2,400 and at max between 11,200-10,900. The only thing I worried about is overheating with all the needle adjustments. After getting the motor to run good I did move the high needle valve forward a couple of clicks just until I could hear it slightly drop rpm( richen a bit). It just seems to me that the needles are closed to much but if it runs good should I just leave it alone?
Thanks
