This sounds ridiculous.
Currently, I am using a quality 2 stroke oil and have my mixture so I smoke a lot at idle but none at WOT with no problems whatsoever.
Everything I have read about using ATF in 2 strokes seems to point to an old school trick that sells worn out 2 strokes and not to proper lubrication and cooling.
Am I wrong, or is this just something specific to mopeds ??
