COMMENTS: If a Pitts style muffler is needed, the J'Tec #JT-60PB (JTCG6970)
            will work, but muffler screws supplied with Tower engine must be
            used, and mounting holes on muffler enlarged slightly.
          For a sport style muffler, use the Bisson Sport Strap-on #00162
            (BISG0162).
          Because of the precision tolerances, the engine feels tight
            before break-in.                                        ir/jl
