ummmmmmm NO . . . please don't open your ignorant mouth until you see what the fuck I am talking about you sorry ass piece of shit who thinks hes some sort of mechanic . . . I have never had black smoke pour from any of my rotaries nor any of my friends when shifting gears or gunning the engine like Joes. Ask Joe I'm sure he will tell you there is something wrong. I was just giving Joe shit me and him, unlike me and you, are cool. Shut your cock gobbling whole until your grow up and know what your talking about.
