The Stihl MS261's

[abikerboy]

Has anybody happened to notice the spec sheets on the MS261's? The specs for the standard non m-tronics shows it to be 50.2 cc (3.06 ci), while the m-tronic versions show a displacement of 50.5 (3.08 ci). I'm kind of curious as to whether they might have a slightly different cylinder, or is this just another "clerical error" between the spec sheets? It would be interesting to see how many components are shared between the standard and the m-tronic versions.
