    This topic has come up a couple times lately. Seems like the fx160 has issues with the ecu. As for brown stuff.......did they overfill your oil?

    Not sure a thought it was flooding because I tried to start it for too long then I saw the brown stuff someone suggested throttle body joint was seeing if anyone came across it before I start ordering parts up

    It’s coming out the top left corner and you can just see the brown stuff at the bottom left

    That appears to be an oily mess being puked up through the intake. Set the ski level, check it with an actual level across the rear and on the side rub rail. Start the engine and let it idle 30 seconds. Shut it off and let it sit 30 seconds. Then check oil. I think it's overfilled.

    Oil level should be checked on a hot motor. When cold, the oil level reaches just above the bottom of the dipstick.

    Overfilling causes oil to enter the airbox and soak the air filter.... but it won't prevent the motor from starting.

    That’s good news thanks so the not firing part should I change the ecu and see how a get on with that
