Default JE Piston

This my friends is what happens when you run lean. After tear down of the motor I discovered that the injector on this cylinder was missing the filter basket. I promptly sent it the entire set to RC Eng and had them clean them and verify the flow figures. BTW JE pistons melt at 1650 F The piston is a JE .040 over piston with Sealed Power Rings. The blow up was on ESPN at the NIRA nationals in Dallas back in 1998?

Ahhh ok!

I saved the pic enlarged it and brightened it up a bit and my guess is they were made by what was left of the sparkplug!
