... and a GS45 ABC at 14700 on 11x5 on 10% coolpower.
Pjtg,
As you wrote, the GS.45 is an ABC engine.
Using them with CoolPower, or with any other fuel which contains no Castor oil at all, is not recommended and may shorten your engine's life.
American made synthetics do not offer the wear and corrosion protection of Castor oil and even European synthetics (Motul Micro 2T, Sachs Aerosynth II/Aerosave), cannot offer the heat resistance of Castor oil.
Start using Omega, if Morgan Fuels is your choice. CoolPower is for ringed engines.
