I finally finished this Ebay project engine. I knew that it needed the valve eccentric strap, but what I didn't know until I started into the project was that the crankshaft was worn, as well as the bearing supports. Also for some reason, the crankshaft was too short and the flywheel was barely hanging on.
I made the new eccentric strap and connecting rod, then drilled everything out for a slightly larger crankshaft, and then line bored the bearings. The eccentric strap turned out to be a very time-consuming part of the project, mostly due to its tiny size and having to make a cutting tool.
It took a lot of fussing to get the valve timing correct, and it still takes a little more pressure to run than I would like, but I have not pulled the piston to check the rings or the valve body. For now, I'm going to be satisfied with having it all back together and running, and I'll probably more on to another proeject for now.
I think that this is a fairly old engine that has seen a lot of use, and I simply don't want to put any more time into it at this point!
