Husqvarna 455 Rancher- are these things prone to ring catch in the transfers?
This is the second one I have been presented with that died in similar circumstances- almost like the ring became gummed (carbon?) into the intake side, near the locator pin and the other side has been forced out enough to catch a port, breaking the ring, gouging the cylinder and chunking the piston.
No air leak, no bearing failure, no lean condition scoring- just a busted ring and gouged cylinder.
Anybody seen similar?
