Bought a 660 stihl clone kit from Hutzl. Went together in 2 1/2 hours. Chain brake does not fit right and handle leans so far forward that it seems to be in the tripped position when not. I had to cut out the bottom of the brake handle to clear the muffler so the brake would work. Cut a few pieces of wood and it ran AWESOME, then I noticed the button gone on the compression release. Shut it down and went to the Stihl dealer to order a genuine Stihl. 2 weeks later it shows up and I put it on. All good. Take it out and cut 4 more pieces of 20" diameter firewood and runs awesome again, then locks up at full throttle while in the cut. I haul it 12 miles home, tear it down and find the connecting rod bearing on the crankshaft is gone. I can lift the rod up and down. The piston had hit the top of the cylinder. All else looked good. rpms had been set at 12,000 and 11,500 under load. P.O.S. saw. At this point I think I will order everything Stihl for the chain brake, crank assembly, and gasket set to put this Chinese piece of crap back together.
