Went thrugh 3 sets of plugs to get back to the landing yesterday. Motor started out running fine, but after running for about an hour it started stalling. The plugs were totally soaked with gas and I could see gas in the water that came out of the exhaust. A used set of plugs got me going again but they fouled out too. I put in a brand new set of plugs and was able to limp back (5 miles!) with it running at about 25% power at full throttle. Sounds like either not enough spark or too much gas. Boy, don't ever go out without a couple of spare plugs!
