[Rhodes22-list] ALICE WEISZ - my comment

[Michael D. Weisner]

Alice,

Although I would not advise going looking for the fuel jet and disassembling 
the carb unless you had an experienced helper available, there is a wealth 
of knowledge online.  I think that you said that you had a Yamaha 9.9 
engine.  Yamaha has an excellent website featuring pdf versions of service 
manuals available at no charge.  Check out the site:
http://www.yamaha-motor.com/outboard/service/viewmanuals/viewmanuals.aspx?ls=outboard

or the T9.9 manual available directly at:
http://www.yamaha-motor.com/assets/service/manuals/1/LIT-18626-07-07_1410.pdf

There are lots of pictures and explanations in the manual, although most 
advanced troubleshooting procedures simply refer you to the Yamaha dealer 
for service.

The site even has an OEM parts center with even more great pictures, 
exploded view diagrams and parts lists at (just enter the product 
line=outboard, the year and model) :
http://www.yamaha-motor.com/outboard/parts/home.aspx

An exploded view of the carb of a T9.9 is attached at the very end (bottom) 
of this message.
