John,
In all my years of engine building, I've never seen the piston pins seize. I'll know more today after I pull the head and pistons out. I'm still not 100% sure the pump wasn't turning, but appears so at first glance. The pressure hadn't registered on the gauge yet in the cab, during the two short times of running because of the very small orfice in my pressure fitting at the block.(a trick I learned from my crop duster friend who is always asking "what if" In his case, a failed line would mean a fire, not good news in the air)
Thanks for your reply
Randy
