And So It Begins....
Ok, I figured it out. The block was high in the area under the crank gear where I relieved it to flatten it out. I removed the idler gear and pinion and carefully reinstalled it watching it as I tightened it down. When I cinched down on it, I could see it pulling away from the crank gear a little bit. I dressed that area of the block until now it tightens down flatly and has a lot less slop. It's very acceptable now in my book. I'm gonna run it. I have a new video uploading I'll post in a few.
