Dave,

I did as suggested and ran 30% heli and no go. The only way to get it to run is have the regulator turned in all the way and it will still load up and eventually die between just above idle and around half throttle. This happens in the air or on the ground.

This is a brand new engine with 6 9 oz tanks through it and based on the thread where Ken Bryant had basically the same issues I'm pretty certain I have the same thing.

Thoughts ???
