I just got this blaster with the top end pulled off and I want to try to put it together as cheap as I can just to hear it run and see if the bottom end is good. I have been checking ebay and craigslist for a used .040" piston for my blaster with no luck. If I can find a piston for cheap, then get new rings, wrist pin and bearing I can save a few bucks. I would also need the clips and a new gasket set. I hate to buy all of this new only to find my bottom end is junk. Know what I mean?
