Break-in of tapered bore engines
Elric,
This "medical condition" of not specifying two-cycle, or four-cycle mode, is common also to other engine manufacturers.
I simply don't know of any other name to call it. The manufacturer of ASP/Magnum, MVVS, Rossi (they call rich; "greasy") and many other don't specify it either.
Their engineers apparently think that us, brain-less modelers do not know our lawn-mower from an electric shaver and cannot determine if the engine is running in four-cycle, or in two-cycle mode....
Strangely, it is OS that I do commend here. Their break-in instructions are/were admitted to be wrong (for tapered bores), but they do state the two conditions in them.
Furthermore, Bax now specifically urges staying out of four-cycle, when breaking-in a tapered bore engine.
