Thread: Gunk coming out of my exhaust...

    Default Gunk coming out of my exhaust...

    After running my jet in my driveway (with a water hose) I noticed I had black oil sludge coming out of my exhaust. It was dripping out enough to pool up on the garage floor. I've never noticed this in the past. Do I have bad gas (keep the Taco Bell jokes to a minimum) or maybe gas that's too rich?

    If 2 stroke to much oil. 4 to much fuel/ look for a possible oil leak.

    First time run this season? Could be your winterizing oil.

    looks to me as if your rings are warn, or the motor did not warm up enough to expand the rings. jeff

    I guess the first question is what kind of motor?
