Engine is running. Thought I would share some of the problems and solutions I have run into.
High Cylinder Head Temperatures. Problem: The cylinder head temperatures, while running the engine, would steadily climb until they hit the yellow zone, and, I would then shut down the engine. Solutions: 1) take the cap off the expansion tank and lower the tail of the aircraft to the ground, 2) pinch off the line between the expansion tank and the overflow tank, pucker up and blow into the expansion tank, and 3) drain all the coolant out and refill making sure there is coolant in the overflow tank. For me, solutions one and two had no effect. While performing solution three, I ran into this:
Yup, I had left the lower and upper plugs in the radiator - so, no coolant was circulating through the radiator. My only excuse is that those are black plugs in a black radiator, and, I was putting on black hoses. On January 7th I ran the engine again and the cylinder head temperatures were right in the middle of the green.
High Fuel Pressure. Fuel pressure had been running 7.7 and 7.8 psi. That is in the red zone. While checking yesterday for coolant leaks, I noticed that the threads on the elbow coming out of the gascolator appeared to be wet. Put my finger on the wet and sniffed - sure enough, it was 100LL. Took the elbow off and applied a good amount of pipe dope to the threads and reinstalled the elbow. Here is a picture of the elbow:
Turned on Skyview and the fuel pump, and, the fuel pressure was right in the middle of the green zone. The threads on the elbow out of the gascolator were dry.
Hope this will prove helpful to someone else when they do a 'search' on this forum. I know the 'search' function on this forum has been very helpful to me during the build.
