Just picked up another Blaster for cheap. Was told it needed to be rebuilt and i was very certain that was the problem since it had no compression. After pulling the top end, i noticed the post one skirt was broken. I recovered some pieces on top so i was hoping it wouldnt be any further problems, so, I put in the new top end and started it and it ran very well. All of a sudden, i started hearing some "squealing" so i killed the engine. I think some of the piston may have fell into the engine? Is it possible to try to flush it out? I appreciate any help and much thanks in advance
