RE: os 160 fuel problem
Thanks Bill
we eliminated all the plumbing probs and this motor only comes with a remote needle we did a test with a 1/2 tank same thing the tank is the one that come with the plane, the clunk is free the vent tube is not touching or blocked we did replace the fuel line that goes from the needle to carb because we felt it was too loose maybe drawing air with vibration no joy
