The oil was hi.. so it was a little meessy.. as far as the 15% I did not give it time to get hot or mess the engine up I let it idle for a long time and ran the engine at 1/2 to 3/4 for some time but I did not run it at full. I will do that when I get me some 10% fuel. I do not know it the 15% will hurt it or not. but I am not going to mess it up..
I was running a 16X8 prop on this 25cc. that is what I ran not it when it was just gas, Is that the same prop to run for the rocking gas/glow?
