Great little engine to fire up!
Had it working some small accessories off the drive pulley, need to have the wick higher though when its working hard.

Denatured Alcohol always burns almost invisible blue for me, and I only start getting yellow in the flame as the fuel is exhausted and it starts burning the wick material.
.... and yes, I always keep my wicks really short and tight on these engines as well.
-
How much water do you have in those Meths Jim, to make that flame so small and yellow?
Zero water Daniel, just straight metho.
I have the wick really pushed in.
With the two desk lights off I think the camera enhanced that yellow glow.
The aluminium tube easily fixed that secondary flame that would come out of the breather hole.
What a fun little engine it is, just a delight to run.

Modified OKMO / Microcosm J07 Miniature Stirling Engine
A very nice Miniature Stirling Engine it was a real 'dancer' across the table turning and spinning on its fuel tank so I cut and put some 4" x 4" timber in my 4 jaw chuck and bored it out to a tight fit on the lathe for the spirits tank and routed it, then stained and varnished the wood plinth. There was also a fairly significant secondary flame flareup from the spirits tanks breather hole when the spirits warmed up enough to create more vapour exiting the breather hole. I extended with a small section of K&S aluminium hollow tube through the breather hole (drilled out slightly) and put a bend in the piping and flared it on the inside for a very tight and snug fit which completely solved the secondary vapour flame.
