fastharry - Your engine should drop in temp over the next 5-10 tanks and you probably will have to lean it out a bit. A lot of the time, my method still leaves the engine with a nice pinch after you run through the procedure which I think is still good as it allows you to spend those 5-10 tanks getting the clutch and everything set just right. From there the engine should run nice and consistant with loads of power.

I used this process on the engine in my RRR and I ran it at the Worlds (1hr), then a Toledo club race (about 1hr 20min) and then all of practice, qualification (approx 50min) and the final at the ROAR Nats (1hr). I would say the engine has over 5 hours on it and all I ever do is just slightly adjust the top needle to get the right mix to match the air temp. Never popped a plug, and tech at the Nats had trouble checking the engine because the pinch was still good enough that it would push the sleeve out of the case at top dead center. Oh yeah, I also used O'Donnel 20% fuel at the Nats!!!

Let me know if anyone has any questions.... I'll be glad to help if I can...
