Runner,
You have to remove the air intake silencer on the front of the carbs to observe the choke plates (butterfly valves) to see if they are closing completely when the choke is engaged.
On my 2000 C115, I can engage the choke with either the remote switch at the console or the manual pull out knob on front of the motor.
When you engage the choke, you want the plates to close completely from a horizontal position to a vertical position. Have someone engage the choke at the console while you look into the throats of the carbs. There should be no gap at the top or bottom of the plates. See if you can move the plates more by gently pushing on them with your finger - if you can, then they are not closing completely. Adjust the linkage to make them so.
Also, check the manual choke knob and do the same for it.
You should only have to choke the motor to start when it is cold. After it has run for a while and has warmed up fully, then to re-start, I just hit the starter switch without choking at all - no extra throttle either.
Now, if it has been an hour or more since I shut the motor down, sometimes I have to choke it to get it restarted. Every carbed Yamaha 115 is different in this respect - you have to get to "know" you motor.
If you want to tear down the carbs yourself, get a Yamaha shop manual to guide you along. Can order online at www.yamahapubs.com. It will pay for itself.
The sponsor of this forum, boats.net, is a great source for parts, including carb kits.
Good luck [img]smile.gif[/img] ,
