Thanks for all the feedback guys. It does sound pretty nasty...
Definitely a fuel issue. Part throttle I can run all the way up to 5000rpms without any trouble at all. Slam the throttle to the floor and as soon as it gets to ~3600 is starts sputtering.
It does get from 1000 to 3600 in the blink of an eye. Can't wait to see what this thing will do with enough fuel!!!
I tok the bird for a little ride yesterday....and again today. Ran very good....as long as I wasn't more than 1/2 throttle!!!
I've been planning to switch to 10AN line...so this just gives me an excuse to go ahead and do it!
