This may be the largest two stroke @ 2.75 cu in., (glow) you can get or more correctly could get and it still sounds like a chain saw. I have two, this one is an Italian built 4500 barely broken in and I have another that I built from used parts in a new crankcase.
Hobbsy,
This engine brings back memories. Had an own design scratch built Super Stinker with a S4500. On down lines it sounded like a Vespa scooter. (For those that have never been to Italy in the 80's or earlier this won't ring a bell.)
Oh, BTW, big 2-strokes sound like, big 2-strokes.
