I get to thinking about things & I get antsy.I managed to get the oil line out of the tank & to my dismay the screen was clean as a whistle.I popped the flywheel off & found the 2 screws that held the pump body on to be loose.I tightened them & tried the oiler & it still didn't work.So now it was time to pull the oil pump off & see what was going on.The plunger & cap stayed on the push rod,spring too.I was left with a bare pump body in my hand.The gasket/diaphragm was stiff as a board.I managed to get the parts off the pump rod & put it back together after a good cleaning.I had it in my hand & the cap popped off & the cap,plunger,& spring went flying.I heard one of the parts,I suspect it was the plunger,hit my kitchen door.I managed to find the spring & the cap,but not the plunger yet.I've got the other diaphragm/gasket in place with the disc in there & the pump body on from the other saw,but can't get the plunger rod to go into the cap & the plunger.Anyone know of any tricks for this?
