Found this out the hard way on a backpacking trip with my son. The red iso butane MSR fuel cans won’t run in my jetboil. Tried it a million times unscrewing and screwing a and messing with the valve. Won’t flow. Anyone else had this problem? Got home and screwed same fuel can into my Pocket Rocket stove and it worked fine. Jetboil website says MSR fuel is fine. What gives?
