I bought a 2110 long-block from Bernie back around 1994, then it sat under the bench in my shop for 5 years before I ever got it out of the crate. I assembled it and pre-lubed it just before I started it. It ran for about 30 minutes, then seized #4 main bearing (closest to the flywheel).
Bernie said he would repair it and ship it back to me no charge, but I had to pay the shipping to get it to him. I thought about it, but then rebuilt it myself, costing me $60 for a set of main bearings.
When his guy assembled it, the #4 bearing was assembled slightly turned and therefore crushed a bit on the locating pins when the case halves were assembled (this is common, and a good assembler will watch for it to avoid crushing it).
Anyway, as I rebuilt it I found that it had been machined and assembled well with the best of parts so I couldn't complain a whole lot, but it should have been checked better before it left his shop for the opposite coast.
I've also found that he was opinionated when I dealt with him 35 years ago and he never got any better (kinda like Gene Berg - opinionated, but usually right). Still, he's still building Air Cooled VW engines, when a lot of guys like him switched over to building/rebuilding Harley Davidson engines just to make money when the VW era slowed way down.
