Hal, Thanks for posting your experiences.
Brian, I have looked at the single cylinder diesels and have come down to conclusion that for smooth quiet running I need to purchase a small 3 cylinder Yanmar or Kubota.
I have received a few PM's from this email for updates. I have purchased my 400 amp 24V alternators and need to write out a check for the powerplant.
I this the two 200 amps with a fancy dual controlling regulator or what did you end up with?
