Interesting little thing.I got a pair of them that wouldn't oil. The first one was just a matter of blowing it out with air and giving it a big drink of kerosine until it cleared it's throat.Filled it up with auto tranny fluid instead of bar oil,gased it up,off to the races.
The thing seems to have ample power for a little saw or at least enough.Cut some 8 to 10 inch stuff did fine.
Now comes the second saw.Evidently someone had pulled the bumper screw then tightened it down on the spring loaded shaft and bent it,no worky.
The way that silly things works is the bumper screw runs the shaft in or out of the pump body thusly determining how much oil the pump picks up per revolution.I can't say I've ever seen any thing like it before.The pump shaft is driven from a gear which is driven by the clutch drum.Drum turns,pump turns ,oils the bar.All the pump actually is,is a flat on the shaft .Who'ed a thunk it.
