Don't take it out just yet....

That Blue Thunder fuel contains LOTS of oil and can make cold starts difficult...

What plug are you running? With that fuel I would say to run a hot plug. For OS I would say an A3... or a #8 if you want to spend the coin, although the A3 is a tad warmer.

If it isn't running hot regardless of tune, flaming out, and EASY to turn the flywheel all the way over with a finger... it's most likely got some life left.
