Motor runs full throttle at 5800 rpm fine. If I back off from full throttle the motor surges severe. It acts as if you pull the throttle from full to idel rapid and will contuine untill I come almost to a stop . It is hard to crank and floods easy trying to crank. Once moving it is ok. Fuel and all filters cleaned , Fuel replaced with mid grade. Vapor seperator cleaned. I cant reproduce this problem in tank or on hose. Ronnie
