[Rhodes22-list] Is there anyone out there who can help mewith myYahmaha 9.9 4 stroke

Alice,
Don't believe the mid grade gas or the additive had anything to do with
your problems.  There is a fuel filter in the motor housing itself.  I
would pull that and see if there is any gunk in there.  Might have
gotten a bit of water in the fuel too, when you pull the filter, see if
there is any water in the fuel filter bowl.  I'd probably also pull the
spark plugs and take a look at them.  Mike suggested checking the tank
vent.  I concur (having made the same mistake myself one time).  - rob

myYahmaha 9.9 4 stroke

Following it's vacation (rehab) in NC with Stan, my Yamaha 4 stroke 9.9
hp with tiller control was purring... 

Last weekend, after 3 weeks of not using it, I decided to get some gas
(had 1 gallon left in the 5 gal tank).  Got the mid-grade at Shell and
added the "blue" West Marine additive (said to add about 1 oz, I did
about 1.5 oz).  Then I tried to start the motor.  After multiple
attempts, I finally got to the point where it would continue to run in
Neutral ONLY at max speed.  As I tried to lower the speed, it would Konk
out.  

 Needless to say... I was a bit 'DISMAYED'.  I took off the cover and
sprayed the carburetor opening with some stuff I've used I've used in
the past (cleaner).. to no avail.

I next opened the gas tank and took out the filter.... cleaned that
(thinking that some 'gunk' - industry term- had settled on the bottom
and was now dislodged.

Again to no avail.  NEUTRAL at high speed runs - but not smoothly.
Obviously if I can't bring it down, I can't switch to another gear.

SO.... this weekend, I "gave back" the gas to the Shell man (you should
have seen his face!!) and got 2 gallons of 87 octane (as indicated in
owners manual) at a different gas station.  No additive... same results.
Put in a different additive...same.   Finally this last additive (Sea
Foam) said to tune-up small motors (2 and 4 stroke) just put additive
straight into gas line (with engine running) and let sit for 5
minutes... then run.   NO change.  NEXT I started to minimally adjust
the idle screw... no help.  

I'm at my wits end and ready to throw the motor overboard... except that
I need it to get into and out of the marina. 

IDEAS???     SOLUTIONS????

Know a good outboard mechanic in the Kent Island area????
