Chainsaw Repair

OK, so we are both stumped at the moment. I have a used good shape pump I could loan you for a test if you would like. Nothing ever fixes itself as I am sure you are aware, but this makes no sense! The only thing I can think of is that the spring and washers on the pump shaft are worn to the point that oil is getting past the shaft and being forced through the pump. I have actually seen 372 oilers that had broken springs and worked fine but could not be adjusted.

If you PM me with an address I will mail you out a pump.
