Just now learning about the Yanmar 2GM20F engine that came with my boat. In blogs about air bleeding fuel lines, esp. when hand-cranking, there are references to "decompression levers". Would someone please help me locate and identify those levers?, and perhaps show which are the "open" and "closed" positions? Thanks.
Yes on top of, well on the side of the valve cover. Closed (running) is toward the front/fanbelt water pump side, open (stopped/ not running) is toward the exhaust side.
