Those later Tecumseh 2 strokes ''with out reed valves'', are great engines,, & pretty much bullet proof, as long as you don't starve them for oil in the mix.
Ones I worked on had needle bearings on both ends of the rod.
I just restored a Snapper single stage snow blow from the 90's, that has this engine, & it still has the cross hatch marks, & great compression !!
Been running ''Tru fuel'' 40 -1 ,& it loves it !
