Shut the engine down using the emergency shutoff -- pull the lanyard clip from the throttle. Re: Raw gas coming from Rinnai tankless water heater exhaust pipe. The next weekend it floods out at full throttle and is blowing gas out the exhaust. It sounds like the motor was in off season storeage & has fogging oil coming out. The plug was covered in oil and I had a small amount of oil sitting in that cyl when I removed the head. This is a new needle and seat but not float. Your car should not have fuel coming out of the exhaust.
