I have talked to Keith and he thought it was airflow. I tried the 3W intake with the hose from the carb plate to the intake. When I installed it I had to cut a large section of the cowl out for it to fit so clearance is not an issue. There is another person with a 115 at our club and he does not have this particular problem so I agree that it is not puddling. I will talk to Keith tomorrow about a new carb.
