I say freshly rebuilt but really just the head; however, I sucked this thing dry. Tilted it on its side and hooked up my oil extractor to the bottom spout to drain the entire ski.

IF I got every drop of oil out of this thing (of course not...but IF); do I understand the manual correctly by adding 4.5 US quarts to fill er up? I'm down here in Houston and plan to use 20W40.

BTW, Thank you for all of your help Tony!
