yamaha carb float adj.

[geo7]

I have a 2001 Yamaha 15 hp that I use as a kicker motor. Model F15eshz. I am going to clean the carb and need to know the Carb settings. Can anyone help me? I need the float setting and float drop. The accel pump adj setting, and needle valve turn outs. Thanks in advance.

Also, just be careful with your gaskets, and no kit will be required.

As you disassemble the parts, screw down any adjustment screws and note the quarter turns. After cleaning, reset the screws to the previous number of turns.

Chances are your float setting and drop are perfectly fine. Most problems are with dirt or 90/10 gasoline trash gumming up in the needle valve. As long as there is no fuel in the float (shake it), just install it where it was.

When you get the engine running, warm it up. Then, look down the carb intake throat to make sure it's not going drip, drip, drip. That's problems with the float and needle valves.

Thanks for the reply. The problem with this carb from the beginning was gas flowing out the top. I have taken off the carb turned it over and the needle would seal. Then it would happen again. I cleaned this carb and installed a kit last year. That did not fix the problem. This year I am trying to fix it again. I called Yahama and they were no help.

Do you know the air mixture screw turn out for getting it started. Thanks
