I cleaned my PAW80, dried it and lubricated it with Hoppe's gun oil from a spray can. Before putting it in storage, I fitted and flipped a 7x3 prop, just for the pleasure of feeling the engine plop freely. Well, guess what, it fired and ran a couple of seconds. I put some more oil in it and repeated the experience. I wonder what is in this oil, or could it be the propellant? I could not find the Material Safety Data Sheet.
All I found is the MSDS for their "Elite" Oil here:
