I’m no expert on those motors but I did adopt a PO-15 a little while back. It had been sitting for years in a shed with no cap on the tank so the kids filled it half full with dirt so check to see what’s inside the tank! The tank didn’t rust because it’s aluminum but it did corrode thru a bit on the bottom and it took a while to get it shiny clean inside again. The gearcase had zero water in it with fresh clean grease. The coil didn’t check out right so that got replaced. The carb float was wrinkled up and separating so I made a new one out of two modern floats which I’ll post in the Members Only section later. The motor has good bounce and the pistons and cylinders look great and the missing tiller came with it but wasn’t attached so the only parts missing to make it complete would be the spark plug covers. Also check the thumbscrews as they tend to seize up over time.
PO 15 as found.
Starting to cleanup well.
Most important, everything inside looks good.
