[>:]YES! I have found after messing with this for hours that the mixture is rich on the low end. when it dies it dies rich and takes a few flips to restart, if it was ignition it would quit in the air from vibration. I found that the low on mine is about 1 3/4 turns and the high is about almost 2 turns, this is after 7 gallons of fuel and the last 3 are Amsoil 100:1, make sure you are NOT mixing this at anything more than 100:1, make sure that you look at the plug after changing the mixture and adjust the engine to get a light brown to a chocolate brown color. not a light tan! too lean. I think you guy's will find your plugs are really dark chocolate color, or almost black. remember that the low will affect the high mixture but not the other way around. these needles will also move under full throttle, I know this after watching it move during testing, a little spot of blue locktite solved that problem also be sparing on the locktite! I found that the low needle was over 3 turns out from vibration and it still ran just fine in the air and did not sound rich. good luck and hope you can get yous dialed in. Rick
