Can you scan or take a picture of your manual? The discussion regarding leaving the drain nipple open or closed during running has never been closed as far as I can see (in this thread).
If Sanye can't agree with themselves , no wonder

I fell in love with the sound of this engine months ago, and it was even better in real life (I bought it to replace my pesky two smoke ''chainsaw'' engine in my YAK 54 30%, I can't take the sound and vibration from those gassers)

I did not check the RPM's yesterday, but I assume it is better to keep the revs down, especially with that poor lubrication. Just hope that I caught the problem in time, I estimate about 40 seconds of running with that noise before I bailed.
Very pleased how it pulled the 21x10w ASP, great throttle response and good thrust.

Btw, I am using Keleo exhaust ring and Microsens 5LP glow system.
