1981 9.9 Evinrude

[goblerblaster]

My 9.9 Evinrude model E10rcid was purchased from a guy that said it was running great- then stopped and he found that the gas tank was full of water. I have cleaned the carb, but did not pull out the plugs that you knock into place in the carb body. The motor is getting spark and will sometimes run for 3 to 5 seconds then die. My question is when I screw in the "lean /rich screw" do I seat it and the put the knob on, or seat it , back it off a turn and then put the knob on? Once the knob is on you can't get more that one turn in either direction.
​
The next question is that how does the "slow/fast " idle knob work.. Looks like there is nothing that can even move since there is a bolt and fixed post that the arm fits on, and I can't see where turning that knob can move anything=== assuming that the parts I am looking at is original.

Since this motor does not have points, I am assuming the timing should be OK since when it does start it runs without missing.

Any suggestions will be appreciated

Turn the low speed screw screw in until lightly seated. Then put the knob on so you can turn it one full turn take the knob off and put it back on the other side of the stop so you can turn it another 1/2 turn. You should be in the middle of the adjustment enough to get started make your final adjustments when it's warm. The idle adjustment knob has a plastic arm coming out of it that is threaded when you turn the knob it moves in and out to stop the throttle arm. There is a curved aluminum arm that rides in the flat of the plastic threaded arm to hold it down. You may have missing parts they break all the time.

I have the correct parts for the " slow/fast" idle knob. I just don't see that anything moves, since the arm has a bolt on one end and a hole that fits over a post on the same arm.. How can it move and if it does, what is the point? There is nothing that I can see that would be impacted even if it did move/

Does the bolt on the aluminum tab also hold the fuel connector in place if so that is just the retainer not the adjuster. What about the plastic piece that screws into the black knob

 

[goblerblaster]

Yes , a bolt goes through the aluminum part into the fuel connector and holds it firm. The white nylon piece that screws into the black nylon knob has a slot in the end of it that fits over the aluminum piece. But, since the aluminum piece has a bolt in one end and a hole that fits over a little post about midway to the white nylon piece, I just don't see how anything moves when you tighten or loosen the black nylon knob.

Put a pic up if you can. The white nylon piece needs to be under the aluminum piece. The flat side of the nylon piece needs to face up and the aluminum piece fits in the flat so the nylon piece moves in and out. The aluminum bracket acts as a keeper to keep the nylon piece from threading out of the knob. The end of the nylon piece will act as a throttle stop for the idle. When everything is as it's supposed to be the nylon piece threaded in the knob will move in and out by turning the knob and the aluminum piece does not move at all. If I can I will try to get a pic of mine up if you can't.

A picture of yours would be very helpful. I have mine off the motor right now. My white pidce at the non-threaded end is flat on one side with a notch in the flat side. I was assuming that the end of the aluminum piece went into that not, but that forces the white nylon piece too far towards the rear of the motor to get everything lined up where the black nylon knob will go through the hole in the cowing straight. Obviously I am doing it wrong !!

Ok I know what you did the aluminum keeper does NOT go through the slot. Now install the knob assembly in the motor completely without the aluminum piece in. When that is done put the flat side of the white plastic up. NOW install the aluminum keeper so the it sits on the flat side of the white plastic piece. When it's assembled the white plastic piece slides back and forth under the aluminum piece you will see how it acts as a stop.

???---That is an idle speed stop.---Allows the operator to select / set a desired lowest idle speed to troll for the big fish.----You do not see much other than the plastic piece moving in and out SLOWLY on it.

Let me know if you still need the pic I will get one later it is raining by me right now.

I think I understand how it goes on now. I will try and get back if I can't figure it out. Thanks for all the help. I still don't see what the white nylon piece controls- unless I'm missing a piece- or it just keeps the throttle lever from closing more or less. I've looked at parts diagrams and think everything is there.

Once you have it in you will see where the throttle hits the end of the white plastic piece that is your idle speed. One thing be careful adjusting the idle speed if you adjust it with the throttle against the stop you can break the knob and push it out of the housing.
