Lets quote some parts from this thread.. they key issues...
You ignored good decent advice given to you from a well known forum member...
Had you have listened to Paul, (very clever fellow - just look at what he has done for the SAU community) your engine would still be going strong.

okay, Who knows what else you have been playing with in your travels... anyones imagination could probly tell a accurate story.
Your engine has been toasted because you put it through hell.
The good news is, rb25's are getting cheap, I will even sell you one for $1,100
