To start things off, I have searched all the threads here for the lack of oil on the bar of my MS-180C and tried all the ideas. I've replaced the pump, supply line, suction screen, flushed the tank, ran the clutch drum backwards with compressed air, blown air back through the oil passage in the saw body, and replaced the duckbill vent in the tank. Also, filled the tank with thin oil such as ATF. The ONLY way it will pump is with the cap off, or to cut some of the duckbill short, but then oil runs all over when the saw is on it's side.
My dealer friend says these saws don't run much oil through them, but I can't get past a 1/2 tank of fuel before the chain is too dry to run. Hold it on it's side and loosen the cap and then cut for another period of time is the routine.
I'm thinking of enlarging the hole slightly that holds the duckbill vent, thinking that perhaps it is choking the valve too much to let air in the tank.
My Echo CS310 goes through about 8 oz. bar oil to a tank of fuel and this Stihl can only put about 1 oz. through per tank, and this is with much goading on my part.
It's a great little saw otherwise, and I know that it can be made to function properly, it's just got me stumped.
Fire away, and Thanks in advance!
