Hi Erhard, my name is***** sounds like you are not getting the fuel out of the tank or the linkage is not moving the lever on the pump to the full throttle position. I'd check for good strong flow from the main hose at the tank and check the throttle linkage to be sure you are getting full throttle. A plugged screen inside the fuel tank could cause the problem.
