The MM2 had very little water left in it so i am glad i removed the burner, the SP1 died first but i only used one skinny esbit in the burner.
MM1 keeled over shortly after the SP1.
These little engines are useless but fun at the same time even by them selves.
The camera makes them sound louder than they really are.
P.S
Always remember to get some steam oil into and around the piston cylinders on all engines :)
