I found the motor manual for my 1995'ish Strikemaster Magnum Plus 10" Ice Auger with Tucumseh TC300 Motor. The manual covers both the Tecumseh model TC200 and TC300 motors. The parts manual is just for the TC300.
I don't see a way to attach a pdf file to this posting or on this site, so I posted the owners & parts manuals here --
