Hi Grumpy, I pulled the pump apart and the only real consumable is a rubber o ring. The pump still works fine. The rubber sump line and filter still seem to be ok.
I'll go slowly as I am unsure how bad a shape the carby is in. I'll see how many gaskets I need and if they are available.
I was going to pull the intake and muffler to suss the piston. Would you go further and check engine internals before trying to start it?
I guess I could pull the head to suss the barrel a little better. Going by the video you need pullers to separate the case. I don't have anything like that.
With the plug removed the engine rotates freely with very little play when rocking the crank back and forth.
