Saw was stored dirty for several years. Oiled fine before storage. Cleaned bar grooves and holes, area around clutch. Drained oil tank and fuel tank and rinsed with gas. Drained again and filled with oil in oil tank, mixed gas in fuel tank. Oil flow adjustment screw turn hard and old oil was partly jelled. Where do I start? Tree service just dumped two tandem dump truck loads of wood in the side yard. I'm not sure the Stihl 021 (15yo) and the new Dolmar 420 will be enough saw!! Worked 12 hours and probably only have 10% cut and split.
