Funny thing, Denny, it was all put together. I had used the wick rear seal and the crank felt way too tight after torquing the rods and the main bearings. As I was going about trying to replace the seal, I fortunately found that the one piston was backward. Like I said, it was fortunate that I went back in. You're right though, it is good to put it together in order. Thankyou for your reply.
