I picked up an old Komatsu Zenoah G320AVS. It seems to have not been well used and is suffering from a fuel starvation problem. When I strip and clean the carb (fitted new carb kit), it runs sweet for a few mins but then cuts out (it did this before installing a new carb kit). If I drip fuel directly into the venturi, it starts up again and then cuts out. There is no primer on this model. If I suck on the fuel line I get a nice tot of premix, so I assume the fuel feed through the tank is fine. Any suggestions? Many thanks.
