I bought my first single mantle JC Higgins off a member here at the Gettysburg gathering last weekend and have had a rather tough time keeping it running decent. It would sputter, flare, lose pressure, go out and if it would run it would be very yellow and not that bright. I bought some Peerless 24 mantles because I read in here these run good with them. Still not any good luck. So just on a whim I put some of my mower gas in it and like the title says it’s 93 octane with PRI-G stabilizer in it. And low and behold, with out any other fettling she’s running bright and white?!? Any one else see this with AGM lanterns??
