Thank you, Clive, for the link. So,I should follow Yamaha 6AH model number and,do not chase for Keihin. At the moment I need manifold gaskets, which are
cheap. And, I may need to change a prime starter assy 6AH-14380-01-00 which is extrymely expensive! The problem I have now is, that the
motor starts normally while vertical (on hook) , but if tilted for beaching it pass the gasand overfill the chamber. So, leaving the beach, I may need to take off the
hood to start it.
