Briggs and Stratton R-tek 2 stroke engine

#3
The R*TEK is really a piston ported version of the reed ported Lawn-Boy Duraforce mower engine.
The PTO diameter on these engines is 63/64ths (0.984375"). Using a piece of .007" spindled stainless shim stock will enable the use of *some* 1" bore centrifugal clutches. I managed to manually produce 1/4" keyways into the Lawn-Boy shafts.
I purchased 2 of the R*TEK engines several years ago and was disappointed in performance. The are now gathering dust.
The Lawn-Boy manufactured Duraforce mower engine is the way to go.
