Hi,
I'm new to these engines! I have one in my fishing boat, it runs my hydraulics. I'm pretty sure its only a few months old.
When I move the throttle lever, the black adjuster on the carb doesn't really move about, and when I close the throttle lever, it doesn't close the carb its about half open. I'm thinking about removing the whole set up, and attaching a push\pull wire directly onto the arm that pushes the carb open and closed so I can control the revs from a few metres away from the engine. Is it just a matter of removing the throttle adjusting springs and the throttle lever or are their more bits I need to take off? Many thanks
Tom

Tommy,

I think you are confusing the fuel shut off lever with the throttle lever. The gray plastic lever is the choke, and the black plastic lever on is fuel on/off.

The large metal lever above these is the throttle lever. When the engines come new, there is a nut that keeps the lever from moving that needs to be loosened. Why not try that first?

If you want the remotle throttle setup, there will be a few things you will need to do:

1) loosen the nut (10mm head) that attaches the throttle lever to the engine, just enough to get it to move back and forth freely. There will be a small spring that brings the throttle back to idle position. Once you let go of the lever it should return to idle with this spring.

2) to attach a throttle cable, there will be a cable stop that either came with the engine, or one that you can buy separately. The throttle cable housing is attached to 1 of the 2 spots (side or rear) that has a bracket to secure the cable, just insert the housing and cable, and tighten the bracket down on the cable

3) insert the cable onto the throttle stop, then tighten the cable.

Kartfab,
Thanks for the reply. I know what levers are what, I just didn't explain it very well.
When I operate the throttle lever, they carburettor hardly moves, when I close the throttle completely, the carburettor is still half open. All the springs seem to be in the correct place.
I'm thinking about installing a wire throttle cable and fixing it directly onto the engine somewhere I'll get another look at it tomorrow. Would I be as well removing the governor bit as well while I'm taking everything else off?

Tommy,

I think im getting at what you are saying. I don't want to make you feel like you don't know what is going on, I am just trying to be thorough (please don't take offense at the below reply).

How do you know that the carb butterfly hardly moves when you operate the throttle lever?

If you are doing this with the air filter off, looking straight down the carb into the engine, you will get what you are talking about. The throttle lever will only truly operate correctly when the engine is running.

If you remove the governor, you will also need to buy a seperate direct throttle kit, and compensate for the governor when starting the engine by holding the throttle wide open while simultaneously pull starting it. I think you may be overthinking this.

Tommy, I'm pretty sure I unuderstand what you are talking about and that does seem to me like it is a normal thing. Have you started and run the engine yet? If you have, when you idle it down, does it come all the way to an idle? When you rev it to full throttle, does it go to a certain RPM and stay? If yes to both of those, that means your governor is working properly.

If I understand, you are looking to hook a cable directly to the carburetor....that would be bad news for the engine. If you want to hook a cable to the motor, it needs to be hooked directly to the governor. Check out THIS PAGE for a little more detail. There are a few different way of doing it.

Hope this helps.

Maybe it's just me, but I think pictures may help this situation...

Forgot to say. The engine was working fine when I got it, then all of a sudden started hunting no matter where the throttle was. It would idle however the revs would go up and down by itself.
I did notice that there was dirty fuel in the tank from the previous owner (I have only owned it for 2 weeks)so I removed the tank and fitted an external set up. I also replaced the carburettor (with a genuine Honda one). It was when I was in about the carburettor I noticed that when I operated the throttle lever it wasn't moving the carburettor very much.
Thanks for all the replies, I will get some accurate pictures tomorrow and post them up.
I'm replacing the exhaust just now and I've taken the fuel lines away so unfortunately I cannot start it up just now.
I'll get some pictures ASAP. Cheers.

I also fitted new springs to rule out the older ones being stretched etc. I'm hoping once it starts up then the whole throttle set up will tighten up and start working. Thanks for the link for the throttle cable idea, definately going to give it a shot

Here's a picture of the spring set up first. Does it look right?
