Dave, I have a 160DZ with about 3 gallons of Powermaster 30% Heli fuel through it. This engine has ran perfectly since the first start-up and the power is unbelievable. The problem started this past Friday. I fueled up and started it as usual, taxied out to the runway and briefly ran it up to full throttle before taking off. When I brought it back to idle, it quit running and I have been unable to get it to run correctly since. I checked all the fuel lines, changed glow plugs (OS F) and nothing changed. I also removed the engine from the plane and mounted it on a test stand to eliminate the possibility of a fuel tank problem. It will start at idle but surges, speeds up and slows down and finally dies. It will not take throttle past about 1/4 without quitting. I've also tried leaning and richening both low end and high end to no avail..........Thank you for any suggestions you may have.........RS

My guess is that the regulator went south. Give Richard a call at service and see what he thinks.
