For dcbdbis:
I think we have all heard of Cox supposedly running an endurance test by hooking up an .049 to a drum of fuel and letting it run until it either runs out of fuel or catastrophic failure occurs. Can you confirm such a thing ? How long did it run? How did the piston / rod socket fare? Was there measurable wear on the components at the end?
It would be interesting to know as part of this thread particularly.....
