While my wife was at work tonight I bought a super nice 090. Tomorrow she is going to rip my fingers off my hands so this post could be my last. Or maybe I won't get up the nerve to tell She Who Must Be Obayed for a few days. In the mean time let me tell you about the saw. It is a very lightly used 090 from a divorce sale. The owner had not run it for years but had drained the fuel after its last use. The saw fired right up but it does not hit full RPM. Compression feels like a new saw, the paint is almost perfect, and the fins are like new. It had a 5' bar and 1/2" pitch Stihl chain on it but I gave those to my buddy who picked up the saw for me. It has a spur sprocket so I'll run by the dealer tomorrow and see if he has rim and drum for it. Oh and the clutch looks new and the bottom of the saw is not scratched at all and neither is the top cover. The air filter had a bit of redwood saw dust stuck to it but it washed out clean with Oil Eater. It is hard to believe how poorly the air filter protects the saw. It does not seem to seal well at all. Maybe I expect too much with such an old design. The chain adjuster is the only part that needs replacing besides the vent hose and grub screw. Well I guess I had better replace all the hoses since one is bad. Is there anything I need to keep an eye on with an 090 (1970s vintage I think)? I will post pics here tomorrow BTW.
