I recently got an ms260.I was cleaning all the junk out of it today.If I let it Idle for 30 seconds or so then rev it up it slings oil off the chain that you can see easily,its alot .The clutch cover is full of oil to.Is there an oring or gasket I need to replace ,this one Is a plain ms 260 so I dont think it has an adjustable oiler.What do you guys think.thanx
