[NSRCA-discussion] YS160 Piston problems

[Zoro1024 at aol.com]

Just wondering if anyone else has experienced a problem with the piston 
cracking arounf the wrist pin boss. I now have a second one with this same problem. 
 It like the first one was running like gangbusters and gradually started 
losing power. On tear down the cracked piston was very evident.  Going to send 
this one baxck to YS with the first piston also.  Looks like the larger piston 
in the 160 is weak in the center.
