Ran the engine today. The first start attempt failed. It lit the propane and started the fuel ramp but failed to ignite on the fuel. We then noticed fuel dripping from the rear of the turbine. We emptied the turbine of raw fuel as well as we could, spooled it up a few times to blow excess fuel out. Then we had four or five perfect starts and runs. One thing I did notice though is that when I pulled the throttle quickly back to idle, The engine was sort of pulsing and hunting rpms. When I pulled back to idle a little slower, this condition did not occur. It seemed to stabilize at a good idle. I will do a few more test stand runs before I install it in my F-86 in a full bypass system
