Put some RTV on the valve cover gasket, taped it in place, and let it sit overnight. Its stuck in place now. This tractor didn't come with pushrods so I grabbed the ones from our parts BR. Turns out the early models used a touch shorter pushrods. This year uses the same as all of the styled John Deere B's. Had a set from a parts tractor that I cleaned and installed. They have some pitting but should work. That made it so I was able to adjust the valves. The new Harbor Freight transmission jack worked great for installing the front cast frame. Still need to tighten it down after I clean up a couple more bolts that I missed.
