Default Homelite DP3-1 Trash Pump

I was given this interesting old pump and would like to get it running again. The 2 stroke engine is tired and needs new rings. The engine runs through a gearbox that cranks a large diaphragm. DP3 must stand for diaphragm pump 3 inch. It will pop but gradually slows down, compression is too low.
Any ideas where to get new rings and a head gasket.
While the engine is 2 stroke it isn't configured like any homelite chainsaw engine I have seen. Possibly it was used to power other equipment, any ideas there?
Thanks
