ok, so it isn't a dry-sump like my friend said, right? holy cow I could have burned up the motor...
I ran out of 20/50 so I put about a quart of some 20/50 diesel oil in there too. then I ran out of oil for the motor so I topped it off with 5w/30. I'm not going to work the machine like this only get it running so I'll let that circulate a bit then drain and fill with 20/50 too. I did notice that this machine has the original fuel pump! I'm sure that's bad so I'll change it too. But I got it thumping so it's going to be interesting to see if everything works. It's an overkill for my small yard but what the Hell...
