All I'm saying is that when people on here are buying these kits, there are usually parts that are missing. Also parts that are commonly replaced with oem parts or better aftermarket parts. So he could have a kit premade for your Chinese kit with all those parts.
I have done enough and seen enough that there are parts you should replace unless you are going to maybe use your saw 50 times.
currently every fuel related part should be oem including carb
piston needle bearing, wrist pin, shorten your ears on the circlips, decomp valve
only use a brake band with a pin
only use the wrap handle or buy a used/new oem to be sure it does not bend like the kit handle can.
I know i am leaving something out
And I was, the rotor and the rope. On the big 660 you might enjoy the elastostart. Nothings wrong with the oiler with a 20in bar anything over you need the 3201 oiler, just like a real Stihl.
