Here is a problem I am having with my kicker. It’s a Yamaha 9hp, I think the model year is 2003. I can pull out the choke and start the engine without any problems. When I close the choke, the engine revs rise up and the engine runs at the high revs. Then, if I try to lower the engine revs a bit with the throttle so I can put it into gear, the engine conks out. Even if I try to lower the throttle a tiny bit, the engine quickly goes all the way down and stops. Any idea where I should start looking? What are the possible causes?
