RE: Sh. 18 and other mods
No four turns out on the Low speed and 2 1/2 to 3 turns out on the highspeed Idle 1mm hole. You need to first get it started and set the idle so it stays running, after you set the idle tune the high speed (DON'T MESS WITH THE LOW SPEED), You want to run it around alittle bit with the body off (don't worry about the temps) and make 1/16th to 1/8th clock wise turns till you get to a point where the engine dies when you full throttle it, when that happens restart it and turn the needle 1/8th counter clockwise and you should be able to full throttle it with no problems and it should sound nice and crisp at full throttle. Once you get set then your going to make small 1/16th adjustments to the lowspeed screws till it takes off with out hesitating.
