Yamaha 9.9 fix

Posted by Dan Hofmann on April 08, 2004 at 06:24:00:

Looking for a fix for the following problem.
You clean and adjust the carb, ( the one with the crank case fumes flowing into the carb intake horn) it is running fine.
You putter around for a couple of weeks and everything is great. Take it on a 5-8 hour run some where and when you pull in it

will not idle. If you adjust the idle screw, you have to run it up realy high.
Thanks

Hi. Had a similar problem and traced it to the linkage. It seemed the spring,on the carb,. that pulls everything back to

idle, wasn't pulling it back enough. I sprayed it with WD-40 while working it back and forth and it seems to have done the

trick, so far.
