2 of them arrived here yesterday.
They look awesome.
I haven't had time to run one yet.
They run absolutely fantastic, but as a caveat, be careful not to overfill the little burner and give it a reasonable cool down time before trying to touch the engine anywhere!
I fire mine in a baking tray with an insolation pad under it, and I also put a little anti-seize on the burner threads then never use those threads to fill the tank, but rather use a fine needle tip on a small hypodermic to fill the tank through the vent hole or alongside the wick.
I ordered my second one from this wonderful sale yesterday, just two days after receiving my first one, but in truth I already had two of these from much earlier in the year, so knew well what wonderful little engines they truly are!!
I may well order a third before this super deal ends, not necessarily because Christmas is coming, though gifting does come to mind, but more likely, just because!!!
