Apologies as I know that my terminology will be incorrect, but I?ve replaced my cylinder sleeves and pistons with a Bare and Co kit to fix water in my oil. I?ve got the sleeves and pistons back in, and I?ve oiled it but when I tighten the rod nuts down, the engine is very tight. I can only just turn the large starter gear by hand. It takes a great deal of pressure. Everything looks fine. How hard should it be to turn the crankshaft?
