Hi Daniel, Now that you have had it for a few days, I have to ask is it a good runner?
I once had one of them that ran good.
DHaven't fired it yet, so don't know how this one is going to run, but the motion feels real good, so I expect it will do well.
Came unfired, missing the burner, so perhaps that is why it has remained a virgin all these years!?!?
I have several burners that will work well with this unit, even the correct one, but I've been giving thought to a small butane burner that I have and think maybe I'll make this one a gas fired Stirling.
Time will tell.
