Interesting that this has come up. I was just searching for a w-1. You mentioned that the truck hasn't been run much, so some of the issue may be that it needs to be on the road a little more. The compression check will tell you some good things and most likely ease your mind some on the previous owners rebuild. I am a died in the wool fan of the carter YF. It solved many of my issues with the rochester -b. They have suddenly become a lot more expensive on e-bay though.
