Pull start engine
Clamped in a vise! This is a big no no.
I see an electronic ignition is being used on what looks like a mag engine.
Running at a high RPM ( sounds to me like ~ 3500)
There is some light smoke in the exhaust ( no mention of fuel, needle settings, oil ratio, oil type, this list could go on and on...............)
So my conclusion is that with the information in this 10 second video with no written info (like a text inserted page with info):
I can not determine (from the video) whether it is running " rich, lean or ideal".
If there was an olympic event in stating the obvious, you'd be the gold medal winner
Considering your "missing info", we're in the gas forum, so clearly the fuel is gas, the needle settings are mentioned in the post just prior to your answer, not that I think that would give you more info than looking at the video, as that would be more individual than most other things, but it's definitely "mentioned"!
Clamping in a vice is no problem at all, correctly done. Perhaps you didn't notice the soft plastic shoes, and you can't see the bracket the engine is in.
Whether what can be seen in the video is "light smoke" or heavy smoke or something else, is all subjective and let's just say that opinions differ. What was interesting to me was what, if anything, could be said about how the engine was running. Clearly w8ye could
as it turned out he was correct, it was running way too rich. Most likely due to an incorrect metering level height, which was corrected tonight. New testruns to be made tomorrow
Oh, and btw, work is generally defined as energy (Joule, or Ws), while foot-pound per second is power (Watt), hence foot-pound would be the "correct" (in your terms) unit for work (energy), not foot pound per second. Also, per definition, even if I had put a prop on that engine, clamped in the wise, it would still not perform work.
