I'm looking for a yamaha 4 stroke expert to chime in and help me!
I have had this motor for about three years. It's been super reliable for me.
Last year while running it sounds like I am losing a cylinder. Then it picks back up. Its very random.
I specialize in outdoor power equipment repairs and have rebuilt the carb several times so I can rule it out.
I have adjusted valves, new ngk plugs, always kept stabilized pure gasoline.
I have pulled the thermostat since it can stick and affect the auto choke system. It was sticking. The oem thermostat is obs nla and the aftermarket equivalent was too long and would not fit into the housing. I was able to clean the old one and verfied it was no longer sticking via a pot of hot water.
Since the thermostat cleaning it does run better but will still lose power and then pick it back randomly.
I have a brand new water pump and a strong pee stream.
Any ideas on what I should do? Any ideas on where to find another source for a thermostat?
