Thanx. Will pick some up on my next HS trip.

I wonder if you got a batch of defective plugs.

My plugs last a long, long time, and I am not the best engine tuner. I'm sure I have had lean runs.

Choice of plug is irrelevant when you are running it lean. :eek:

Any new update on this?

So far so good. Went with an 8 and richened it up until I could see just a little smoke out of the exhaust. Flew four flights today and before putting it up, Ipulled the plug and looks good. Guess time will tell. I wont be able to fly again until this weekend so cross your fingers that all goes well. BTW, thanx for asking.

Awesome dude keep us posted. Im confident your problem is solved

all the OS 40 to 60 size engines at my LHS #6 plug in the box with the engine. The owner tells me this is the running in plug because initial settings are rich and the #6 fires well under very rich conditions. They do burn out quickly but he reckons you should be able to get a full gallon through the engine before that plug will need replacing.I think he is right because I got a gallon through an OS 46Ax before the plug burned out. Its easy tosee a burned out plug, the platinum coil looks white. Replaced it with a #7 and the engine hums along nicely. Have around 25 flights on it now.

Thanks to all that helped here. You guys probably saved me from having to buy another engine (hope I havnt hurt it too bad).
