Guy has a big set of brass cahonys to stand next to that thing choking the air from it with a pressure tank "Missile" and hose and regulator valve just inches from the flywheel.  

Here is the actual video without the dumb music and a better description of what was going on.

This video illustrates what happends when these two stroke semidiesels run out due to too much oil in the crankcase. With my left hand, I block the injection pump, so from that time the engine run on lube oil only, no diesel at all. I have heard lots of stories about this from decades ago but this is the first time, to my knowledge, that it is captured on video. Luckily we had blocked most of the air intake prior to starting and ended at somewhat over 1000 rpm. Max operating rpm is 425-450. With full air supply, I would guess this engine would reach thousands of rpm and I could only guess what would have happened then...

The electric glowplug short circuited so we had to rely on the propane burner which had slightly low temperature. In this startattempt, we used an acetylene burner and got the glowplug bright red. The crankcase was, unfortunately, filled with too much oil so the engine was running on its lube oil from the crankcase instead of diesel. Still some trouble with the fuel injection, doesn't feel right when injecting diesel manually

And the successful attempt at getting it running, sounds pretty good too.

Took away my fun.

You are so mean...
