You'll be the first to know
OK, two more tanks today for a total of a bit over 12 minutes so now it's had 30 minutes all up. The piston still binds at the same spot and there's no change in tip movement on the prop as my rod wear indicator. The only change I've seen is a tiny polish mark about 1/16" down from the top of the piston and less than 1/8" across. Even then I only noticed it at the last minute when I held it at a different angle and the light reflected off it.

But now I'm starting to wonder just how long I should run it like this and what to do with it next. I'm of a mind to treat it more or less like a ringed engine and slowly start leaning it out, at least to the break into a 2 stroke (which I accidentally did today when I forgot to put the pressure line back on the muffler...DUH!). I'll give it at least another two tanks (12 minutes) because I want to watch that polish mark. Right now I'm just about satisfied that the rod isn't going to snap and that the piston isn't going to tear itself to pieces but I'd welcome any constructive comments on anything else to look for or maybe how much longer to continue trying to destroy it

BTW, if anyone would like to donate a Jett or Nelson I'll happily carry out the same test on them
