throttle stuck

[staxbrix]

I took apart the carb to check to see if the float is working. When I put it back together the throttle wouldnt budge. When I loosened the cable to get some play, the tension brtoke part of the plastic where the cable goes in. Still dont get much movement, whats wrong?

[TUG]

wo its ultra tight with no play at all?
is it wired to the carbs propperly? are you sure you've put it back like you got it? take a few pics to help us out.
what bike is it?

If you haven't touched the throttle at the bars or moved the cable then it MUST be something you've done at the carb, you musn't have connected it back up correctly.

Ill have to post the pics in the day, when I check the slide to see if I put it in backwards. I have a little play now that the part broke lol, but the throttle will only turn slightly and doesnt move back proper. I dont want to start it if its stuck open or closed.

Any other reason this would happen?

[TUG]

you've put it back together wrong.
is it a 2stroke or 4?

2 stroke, I think khelin carb? The only problem I had trouble with is the spring and slide on the top. Im looking at that first thing in the morning, I ran out of light today. Is it possible i need to lube the top part up?

Also the carb was overflowing alot so I checked the float and everything looked good maybe it was stuck before I took it apart. I didnt add gas cuz of this problem but im not sure if I solved the overflow issue. If that doesnt work can I just bend the clip a little?

[TUG]

did it go in on its own or did it need force? if you forced it a bit then you put it in wrong, thats what i did.
did you take it completely apart or did you leave the needle/slide on the end of the throttle?

I think what you need to do is take the throttle valve out, check you haven't bent the needle then put it back in properly this time.

If you're utterly convinced it's in right and it still won't move, check the twistgrip end hasn't come adrift/hooked-up.

It went in half way fine the other half was a little forcefull but it was puzzle shaped it could only fit one or two different ways so I thought it was right. It didnt move much and it was hard as hell to get the spring compressed to close it.
I didnt take it all the way apart just disconnected it and pulled the float bowl off and cleaned it up.

How would i inspect the twist grips?

[TUG]

think you've forced it in the wrong way to be honest with you.
you got a manual for it? or know anyone who has?

I have a manual for a 89-94, Its mostly part diagrams. Im not sure if its the same exact carb in my 88. i think thats were i messed up or some how the cable/ twist grip/ was damaged. Any info on what to do tommorow will help? besides see if its in right.

[TUG]

strip and reffer to the manual unfortunatly, if its not the same carb used then use it as a kind of how to put together diagram. putting it in like you have might make it harder for you to find out which way to put it back in is correct. also if its stuck closed is gunna be really hard for you to remove it.

The throttle valve should drop straight in all the way to the bottom if it's in correctly, no force necessary at all.

I'm concerned that you either have it in the wrong way round or that the needle didn't go down into the main jet (I remember it being a bit tricky to line-up on the flatslide carb on my brothers DT125). If this is the case, you could have bent the needle by forcing it which means you'll most likely need to get a new one.

I'd normally suggest removing the needle and rollng it on a sheet of glass to check it's straight but in your case, I'd suggest you get someone with more mechanical experience to help you.

I didnt have the needle in the jet. How will I know if the needle is ok?

Im still haveing the overflow problem, I lowered the floatl as much as I could without the needle sliding out. So as soon as I put in gas it starts dripping steadily.

[TUG]

put it on a falt surface and roll it. you'll know if its bent.
what you mean it wasnt in the jet? was it not in the the slide when you put it in or you missed the jet when putting it back in?

PUT THE SCREWDRIVER DOWN AND STEP AWAY FROM THE MOTORCYCLE SIR!

Now think. You adjusted the height of the floats so you've looked at all the stuff in there. How would it have moved all by itself? Fact is that fuel overflow is rarely caused by the float height moving. It's usually either a sticking or punctured float, a dirty or worn needle valve seat or a sticky pin in the top of the needle valve.

Trouble is you've now moved it, you are going to have trouble putting it back where it is supposed to be once you've fixed the real problem.

The throttle needle and the needle valve are not the same thing.

I suggest you have a look at a workshop manual and check out some online guides and diagrams to check out how the thing works, what the various bits are called and how it is supposed to fit together before you touch it again.

the throttle valve wasnt seperated from the needle and was in the correct way but I didnt have the needle properly seated in the carb.

I do have a manual for a different year and it implied the float controled the level in the carb. It doesnt have much of a troubleshooting section. The manual also tells you to strip it down completly but doesnt show you what a bad needle or float looks like. I could tear down the whole thing but im a bit unconfident.

I think I might have lowered the float instead of raising it now that im looking this over.

Im no mechanic but im competent to do the work with direction, I mantain broilers for restaurants nightly and do most of my car work.

I took pics only the outside of the carb came out.

stink wheel if he breaks it its his bike lol mistakes will only cost him money not you, and the only way to learn is to do.
i think its time to check the needle and the slide and the float height. but before that, you need to find a manual for the year bike you own, unless the manual states the same carb you have in your model your ok. the link to your pics isnt working too btw.

Well. if you're totally happy you can put it back in again, remove the throttle needle from the throttle valve and remove the circlip. Pay close attention to which groove it is sat in so you can put it back in the same one later.

Roll the needle along a sheet of glass. If it is bent, it will be immediately apparent. Inspect the point with a magnifying glass to check it isn't damaged.

Reassemble the throttle valve assembly so it is hanging on the end of the throttle cable and move the twistgrip, it should work as normal. If it doesn't, the problem is with the cable or how the cable is seated in the twistgrip.

When you put it all back into the carb body, it should drop straight in all the way to the stop. If it doesn't, it isn't in right, either back to front or the needle hasn't dropped into the main jet. Never, ever force it in.

When looking at your needle valve, check for any bits of grit or dirt around the point of the needle and the seat. Inspect it under a bright light with a magnifying glass to check for wear or damage where it seats.

Some needle valves have a small sprung pin about 2mm long in the blunt end. Make sure this can move freely.

Take the float(s) off and shake them. If there is fuel inside it is punctured. Put the float in a bowl of water. It should float and be perfectly level. Push it under the water and look for any bubbles coming out of a small hole. Dry it after.

Leave the tang where you've got it for now, you've adjusted it so the fuel level is too low which will be easier in terms of checking the valve is sealing.

Reassemble and connect the fuel. If fuel still runs out, gently but firmly tap the side of the float bowl with a bit of wood or a deadblow hammer a few times. This often frees up sticking floats (the fuel would stop).

That SHOULD sort it, otherwise you're probably going to need to replace the needle valve.

Once you've stopped the leak, fit a length of clear hose to the carb drain spout, bend it up alongside the carb and crack open the drain screw. The fuel should move into the tube and up to the level it is sitting in the carb. Your manual should have a measurement showing how far up the fuel is supposed to come in relation to the lip of the float bowl. Adjust the float height as necessary.

Just to clarify the twist grip throttle works after I assembled it right. Ill check the needle and try to find if its the same carb.

this isnt going to help much its just the outside.

keep a good head on too and dont lose your temper like me, it always costs more.
hope ya sort it mate cos when you do it will be like a new bike.

I shooked the float and no noise and then put it in soapy water no bubbles and it floats.

Im stuck now it keeps overflowing. Im trying to get in touch with the mechanic next door at first I was reluctant cuz he told me to just plug it up. Wouldnt that leak the gas into the engine?

[stinkwheel]

Yes it would.
