That's running your Baker fan without a care in the world Bruce.
What's kind of neat Jim was that I am running it right now & went through a tank of fuel (noticed the flame was burning out) took the pot out , filled it up again & put it back under without the engine even stopping , & I wasn't trying to finish before the engine quit running, that thing has amazing sustaining ability.
I consider this engine one of the best values per funds spent.
What should I use (if anything) to lube that brass cylinder assembly ?
