So, I am rebuilding the pump/cylinder on my '48 8N and ran across a few things that I don't fully understand. Take a look at the associated pictures…
1. Am I correct in thinking the control arm should be STRAIGHT?
2. The draft control pin is broken (probably explains #1) and the Steiner girl says its a .490" dia pin, but I can only find 1/2" and 5/16". Which one is correct?
3. The pump control valve had a "button plug" on the end of the intake valve. However, mine had been replaced with a regular washer. Is this acceptable? If not, where can I find one? It's #27 in the pic.
