I tore down a 11 horse Briggs identical to that last winter. It was all worn
out. The Syncro balanced thing was interesting. Basically 2 heavy weights
that hang off either side of the connecting rod on the crank. Crank turns
freely in them so the just hang there. I have to admit I beat the heck out
of that engine for 10 years, and it was well used when I got it. As was
said. If the price is right, go get it.
