I have completely disassembled the engine and found what I think are quirks of a fairly early (W-1785-8) engine. First, the timing chain adjusting plate is of the early large-tooth style with two buttons as seen in this post. It only has one hole in the face of the plate, so the conventional adjusting tool won’t work. A previous owner had apparently used a hammer and a drift to make adjustments, so the plate is pretty well buggered up. Unfortunately, I can’t find this early type plate anywhere. Does anyone know of a source?
Also, once I get a new plate, what is the correct way to adjust it? I can’t really fault the PO since no other adjustment mechanism is obvious to me.
Second, There are no upper chain dampers. There are what appear to be factory spacer pieces that go where the dampers should go, but no dampers. Is this correct? Should I retrofit dampers?
I apologize if these are common-knowledge question. I couldn’t find any useful info elsewhere and I’m still learning.
