I have a new 56 with about a gallon of fuel through it now (20/20YS blend) and I cannot get this thing to idle low enough to not pull the plane around when sitting on the ground. It will idle down to about 2500 for about 10 seconds and then sputter and quit. Ive played with the needle setting, and changed the glow plug to an OS type F all to no avail. Any advise from you Saito guys would be much appreciated.
