Can a C-15 cat engine burn fuel?
Can a C-15 cat engine burn fuel? It's not the same as an "E" or the first C15's (6nz) there is absolutely no power above 1500 and running one there will do nothing but burn fuel. You say it's getting hot but you never said what the temp is. What causes a C-15 cat engine to spin faster? Downshift until you are pulling under 20 PSI on the manifold pressure and have your RPMs over 1600, this will cause the fan to spin faster and cool better. As for your fuel mileage, that is very common for an ACERT. Sounds...
