I have a 1969 9.5hp Evinrude. It has been a great motor since i bought it 2 years ago. I had ran it a few times this year with no problems. A couple weeks ago I went out fishing, started it up and it ran for about 30 seconds. Then it died, at first i thought i may have flooded it....not the case. I have traced this back to the carburetor. I am getting spark and gas to the carburetor. I finally dumped a small amount of gas down the carburetor and it fired right up till gas ran out. I am not the most handy person when it comes to boats, cars, mowers, etc. Can anyone help me with where I should start of what I should replace?

Re: 9.5 1969 Evinrude

sounds like the float is stuck shut, or you have a blockage somewhere in the carb. Carb needs to be cleaned and rebuilt in my opinion.

Is it a difficult task for a novice to achieve? I have found the rebuild kit for $30.00 plus shipping. If not to hard do you know where I could find a manual or just this section on how to do this.?

Could be fuel line connections, pin hole in fuel line, fuel pump if it has one, pick up in tank blocked. There are lots of things to check. I would start by holding the intake to the carb closed with my hand and pulling rope to see if it will pull fuel that way.

Rebuilding carb is a relatively easy task. When you are ready we will talk you through it.

Lines look good and it gets gas all the way to carb. So it shouldn't be the pickup in the tank? Not sure i understand what your saying about pulling fuel

Rebuilding a carb takes some mechanical know how, If you feel comfortable with doing it yourself, then by all means go for it. If not then you may want to remove the carb from the engine and take it into a marine shop to have it serviced thier. Thier is a website with good parts breakdowns for many years and models. You should find info here about parts breakdown of your carb.

Go to "Evinrude" then "1969" then "9.50" and select your model.

When you block off the intake the vaccume developed by the piston and crankcase will pull fuel thru the jets. If it is just a minor something clogging the jet it just might pull it clear, done it many times.

Ok i probally shouldnt try to tear the carburetor apart because i dont even know what you mean by holding the intake open. What is the intake and where do i locate it to hold it open?

Let's stand back and take a deep breath here.

Okay, we need to determine if you're getting fuel to the carbs at all. Fortunately, this carb drains out the float bowl when you tilt it. So it's a pretty easy thing to figure out.

Pump it up with gas (squeeze the primer bulb on the fuel line).
Take the cover off the top.
Tilt.
Does fuel come out of the carb anywhere?

That points to one of several things, the most likely being a stuck float needle. But, possibly gunk in the line or fuel pump.

Now, disconnect the gas line from the carb and pump the bulb. Does gas come out of the disconnected line? If so, it's the carb.

Re: 9.5 1969 Evinrude

Ok yes the fuel comes out when i squeeze the ball, so it is the carb. Would you recommend rebuilding the carb?

Yes. Order your self a rebuild kit and get cracking.

I think when reload says "holding the intake to the carb closed with my hand" he means essentially to try choking it so it pulls fuel. As far as the rebuild, it's not hard, and those little carbs are simple to remove and rebuild. See pics of my 1971 Johnson 9.5 HP carb I just rebuilt and hopefully that helps some.

The first pic is of the disassembled carb. The top part is the base containing the float chamber and is screwed to the intake with 5 bolts. To the right of that is the high speed jet and a drain screw. The bottom part is the carb itself, attached to the base with 4 bolts, the cork part is the float, just to the right of this is the brass needle and seat that allows fuel into the carb. When it gets full of fuel, the float rises and pushes up on the needle and shuts off the fuel flow. The right of the needle seat is the high speed/main jet pickup tube. Between these two is a port for the idle mix. The big rod shooting out to the left is to open the butterfly on the carb, to let more air in, so it pulls fuel into the cylinders. The roller on the end of that rod rubs up against a cam on the magneto base just under the flywheel and open the butterfly on the carb when you twist the throttle.

The second and third pics have an arrow pointing to the idle jet. It should be set 1 1/2 turns out after being seated to start. When you take the carb apart, you'll want to make sure and blow out all the little ports with air, or maybe even soak all metal parts in a carb cleaning solution. The main jet typically has a hole .048 inches in diameter and you can check with a drill bit and calipers. HTH, and a manual is good to have, even one from a library.

One more thing . . .

Only the OEM kit has the float. It's worth replacing the older cork floats.

Re: 9.5 1969 Evinrude

I have spoken to a few places about my carb. One place wanted $350.00 for parts and labor. Can you beleive this? So i dug up the number of the person I bought the motor from and he also works on them. He said it is probally a stuck float needle and I shouldn't need the rebuild kit. Anyways I am taking it to him to look at tomorrow and even if he determines it needs to be rebuilt he said 50-75 dollars plus the $35.00 kit...much better than 350.00! Thanks for all your help and I will post again once I find out exactly what it was. Please let me know if you have any more imput.

If he is going to charge you to take it apart anyway you should just as well have him put in new carb kits or else you might be paying him again next year and then you will have to pay twice.

Re: 9.5 1969 Evinrude

That's good advice. The kits come with new float needles and seats. There's a reason it's sticking.
