My experience with bag nitro gas was realy baaaad, it cost me an engine.
to make it shirt I was running an IDM Picco Evo2 and at the middle of the main the engine was realy slow and I make a pit stopfor surprise the temp was 400oF and for surprise the engine was smoking realy good so my pitman open 2 complete turns on high needle, I continue to run , the engine continues to run slow and the same temp when refueling and a lot of smoke cumming from the pipe, the engine never stall or flame out, but at the end the engine compression was gone the piston was melting, and the engine rest in peace on the Engine heaven end of the terror story then I change fuel brand
