Wondering if anyone can help. Received new 21 lpm loncin pressure washer earlier today. Was going perfectly then suddenly stopped. Can get it started but after a short period seems to cut out again. Topped up the oil plus unleaded petrol. Just wondering if i m doing anything wrong. Putting the revs to about a third of the way from the slowest Putting the fuel on. Choke closed then opening as engine starts up and machine switched on. Wondering if i m missing something. Two hose things the outer bypass plus the one that picks the water up in a wheelie bin full of water. Does the hose providing the water from the tap need to be on at all times any help greatly appreciated.
