Wow I didn't know this thread was still active, right on.

PattonJR, the engines can be a little finicky and down on runtime until they break in. Its ok to run them in the 250f range at this time as long as you don't hold with WOT for long stretches until the engine get about 1-1.5 gallons thur it. Just go easy on it remember its still in the break in process.
