I've recently observed that old fuel (atlest fuel with RIO in it) has a
limited life span in terms if usability. I tested some old motors that had
RIO in it and they all katoed. I also has some old powdered fuel used for
making hand rammed motors and the the motors that I make now with it all
Kato. I made new fuel and it worked fine. I suspect that maybe the RIO
catalises some side reactions that makes the fuel become unstable? Anyone
able to shed some light on what's going on here?
