I have a couple trees to take care of before they leaf out. My 1975 Stihl Farmboss needs a little TLC. The muffler is loose on the 4?mm screws to the jug and the root cause, the stabilizing outboard screw on the muffler is missing. The original gasket is intact but very tender. I was hoping to go downtown and get some external toothed washers, a 3/16 nut and screw. And be cutting wood Sunday. I'm dithering about getting a new gasket if I can get it locally. If not I'll slather it with silica cement and snug up the screws.
ATTN: 100:1 mix boys. The Farmboss specced a 40:1 Stihl oil. I used Stihl stuff mixed to 32:1. since day one. Then the local guy closed, so I used True Value or what ever for the next 20 yrs. Now I'm on my 2nd qt of Valvoline universal mix oil. The saw hasn't been used in 6 months at least. The side of the piston was coated in oil, sticky slippery oil. It looks great. No carbon on the port. Muffler is just a hollow box. No restrictions.
