No much explanation is given, regarding the fault and the model number. But a general answer will be to check the idle speed of the engine. Also try the machine with the gun removed. If it continues the fault....it is from the engine....if the fault stops, it is from the pump. These are very simple guidelines. By simple elimination, one can at least detect from where the fault is actually happening. Regards, MG.
