So I worked out a deal dangling an older 10/2 lister under Butch's nose and left with his National, not without adding a little to the pot of course. It is such a beautiful and well built engine I just feel if I passed it up I would seriously be kicking myself in the butt later on. Once I got it home I decided I was going to go through it and tighten some things up on. I ended up getting a new wrist pin made for it out of 4140 hardened ground and polished, I made a new small end bronze bushing. Im getting the crank mains polished and the con rod journal ground round. I also put new rings in it and the first ring grove was a tad out of spec so I trued and widened the grove so I could run a .030 spacer. All in all the engine is in excellent condition but it had just been ran a little thats all. One thing I felt was interesting is I took the fuel pump apart to review the internals for signs of wear and it looked new, but hear is the the interesting part it has a 8mm fuel element. So in perspective Dads Ruston 1xHR has the same as my Listers 6.5mm, the displacement on the Ruston is 186CI and the National is 213CI. So its not that much larger of a engine to have that much more fuel going to it, maybe that explains whys its rated at 13Hp vs the Ruston which is only 8hp.
