2000 Yamaha 115 2 stroke hard to start

[pappastratos]

I recently purchased a boat with a 2000 Yamaha 115 2 stroke. I checked compression, it is fine. When we tested the motor, the owner attached the hose, squeezed primer ball, started right up. Had not been started that day. When I get it home, it thinks it needs government approval to start ! Spins over fine, just will not fire. I hear the choke activating. After about 10-5 second tries, it finally starts to fire a little. Then next try a little more, then a little more, then it will start. When it is warm, it starts immediatially, but if it sits for a hour or more, back to hard starting. I do not smell gas, so it does not seem to be flooding.
I prime the ball, hold choke in, turn the key. Seems do do better if throttle is not advanced. Any ideas or starting procedures ?

Sounds like a reed-valve issue.

Try pulling out the manual choke knob on front of lower engine cowling.

I will try the manual choke this weekend. I will check that the solenoid is fully closing the choke. You can hear it close when you press the key. I also will check that it is staying closed when I "start" the motor. Could it be possible that the switch is not keeping the choke activated when I start the motor ? Boat is from a coastal environment.

It was the choke solenoid that was out of adjustment. Choke was not closing all the way. You have to remove the solenoid when you remove the air box. Previous person did not adjust back to orginal position.
