Does the Stihl MS193 use the same motor as the MS170?

I read somewhere that the predecessor of the 193 had the same clamshell motor as the 170. Is this still the case with the 193? I can't find the 193 IPL.

I am not absolutely certain however I believe they may share the same crankshaft, bearings, and a few other internals. Cylinder is different though. Someone who knows for sure will hopefully post what's what.

Cylinder is different, 192 is a 90° intake/exhaust with carb on top with cylinder horizontal and 170 is straight across with cylinder upright , I think piston and rings are the same
