      Garry, I believe I have the same information in the manual, but
      glad I reviewed yours, as I don’t remember reading that
      when you drive in a new insert with a lead seat installed,
      you’re suppose to drill out the lead seat with a 5/32"
      bit.
      Makes me wonder if the new lead seat doesn’t
      have a hole, or it does, but it needs reamed out
      after being "squashed"?
      Thanks!

      Prepare to be boarded!

        The lead seats arrived today. They’re little lead buttons
        that need the hole drilled after installed and seated.
        Unfortunately, I think it would be best to do this
        when the crankcase is "split", to avoid lead shavings
        ending up in the crankcase, and / or accidentally
        drilling into the crankshaft.

          Thanks Buck. I might attempt to make some now with the given dimensions.
