Just ordered a new oil pump and pickup for my 4620. Saw is nearly new but was not pumping much oil so I pulled the pump and pickup out but saw no issues so I’m going to have to figure the pump was faulty. Maybe this is why the saw had nearly zero hours on it.
Can’t wait to get it up and ripping again. Was a strong runner but wasn’t oiling.
The older ones were two piece and would swell and cause air leaks. If you have the one piece where there is a hole in the rubber block that slips over the pump shaft then it likely is the the pump. The older ones were two piece that were split where the pump shaft was.One, I think. Molded pickup that goes into a rectangular rubber piece that seals the tank off.
Is that the recoil pulley that fits a 3750? And, if so, will you be selling it?Tore into the Pp380 that was in the new stash.
Can see a torn intake boot took it out. Still even had the plastic epa stops on carb.
I'm just going to part it out I think. Looks like crank area had moisture from weather changes setting over time.
Cylinder will clean up easdy. Piston I could fix and use myself.
