Ran the 8Hp last night in a trash can to see how it runs. Seemed to work great. This morning I go out and notice a black small puddle under the prop on the floor. It looks like it was leaking out of the prop. Took prop off and noticed this gunk on the inside as well. It's very dark and smells like gas as well. I'm hoping this is unburned oil from the fuel. I'm using the amount recomended for break in 25:1 Please tell me this is all this is!! The motor is BRand new!<br /><br />Joe
