Here is my Routine for a really dirty saw, or just cleaning up a saw to as clean as it can possibly be. Ive done A few Husky's, lots of Stihls, Lots of Echo's, and so far every customer was shocked and elated as to how well it turned out.
Remove bar and chain. Sharpen chain, clean kerf with a scraper, then blow out, clean sprocket tip, blow out, oil.
Remove clutch. Sand shoes, sand inside of drum. Clean and lube bearing.
Remove top cover, remove air filter, remove muffler. Remove carb.
Drain oil tank, drain fuel tank. Remove recoil.
Soak entire saw in solvent, I use BIG RED with a heavy concentration mix. I let it sit 5 minutes, then power wash the whole saw, bottom, around the head, where the carb would be, where them uff. would be, around the flywheel and coil.
Then I bring it inside, soak it in brake cleaner, and hit the whole thing with compressed air until totally dry, then I let it sit in the sun an hour or so.
In the meantime, I clean up the recoil, powerwashing it, as well as the clutch cover and the top cover.
Bring the saw in, drip some oil down the intake power, and into the exhaust port, I usually hit it with a fog of WD-40. Then I cleanup the carb, usually rebuild it while Im there. Bolt it on, put the muffler on, recoil on, clutch on, bar and chain on, new plug, top off the fuel tank with fresh mix, also checking to be sure no water made its way into the fuel tank. Same with the oil tank.
So far, all sqaws have fired within 5 pulls, and ran as good as new.
I can do a really really nasty saw in about an hour and a half, from setting it on the bench, to making out the ticket for repair. Usually charge anywhere from 45-55 dollars, depending on how big the saw is, and how nasty it is. My commercial customers love the service, it keeps the saws happy, and it keeps the users happy...that makes me happy.
