well I finally managed to get a gallon and a half on my engine. Took out the break in shim and retuned. Now I dont have any problems making the 7:30 mark at 230 with the 7mm insert. I beleive I have almost a 1/8th of a tank left after a 7 minute qualifier. Never got to the mains though got rained out so hopefully in a couple weeks I can push it harder and see how long it goes.
