Somewhere, though finding it may be difficult, I have a 1960’s-era scientific paper that was submitted by Silkolene Lubricants to an unknown university (?). The main topic is plug fouling in deflector-piston two-stroke engines, but it includes other issues that may play a part in the general running characteristics, such as fuels and ignition timing. I think that Scott engines got a brief mention, but Mercury outboard engines are the main player. Both fuels and lubricants have changed a lot in the half-century since it was written, so perhaps we ought to now ignore it, but if I can find it I will read through it again and see if it could form the basis of a Yowl article.
I just love how a little remark on this website can kick off a flurry of very interesting replies !!
