Andy, could you stake the seat into the block? I don't know much abvout <br>
Onan engines, but it swwms to me that this would be an inexpensive fix <br>
vs. a replacement engine. Also if these Onan engines are prone to this <br>
failure, there is probably a fix available for the issue.<br>

My 2?<br>

<div class="PlainText">Thank for the answer Phil, the trick fixes like staking the seat into the block have already been tried and failed. There are oversized seats available but I would have to tear the engine down to have the block machined for the new seat.
I may be able to switch engines easier and cheaper. I wish I knew and easy way to machine the block for a new seat without a complete tear down. </div>
