if i tilt it up while idling and it dies it is rich? rich in air or fuel????? because to make pass the test, i have to close the air bleed screw in so that there is less air in the carb. but that always messes up the high ends.

So if i get it to where it has great high ends and doesn't increase rpms when it is tilted up at full throttle, and it will idle on level ground forever, it should be okay? i always was told to tilt it at full throttle and idle. if it does increase rpms when tilted up at full throttle, is that bad?

the fuel tank is a hayes 11 0z. tank. it sits right behind the firewall with the fuel outlet nipple slightly below the centerline of the carb, no more than 1/4 th of an inch. If tuned to run good at high ends, it runs great in all aspects, right side up or upside down.

by the way, the airplane is a hangar 9 .46 twist.
