The overflow problem is a carb float being stuck open. Turn off the gas and drain the offending carb(s). Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times doesn’t free the float I would remove the offending carb(s) and clean with a spray carb cleaner. By the way, Check the float, it could be filled with gas instead of air. Clean the air filter then re-mount carb(s). Next, remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an in-line fuel filter.

The lack of movement in the carb slide is either a bad cable or the the carb is a CV model. The slide on a CV carb will not move unless the motor is running. Start the motor. Does it speed up normally when you twist the grip? If so, then there is nothing to worry about.

Twist grip throttle stuck at idle


Hi George. Brad may be right with his answer but there might be something you can do.
Does the throttle open/turn as it should or is it stuck in the closed position and will not turn at all?
If it won't move then it could be a seized cable, a stuck mechanism at the carb end or a twisted or kinked cable.
If it does move but the engine doesn't rev it could be a broken or disconnected cable.
On top of the carb there is a mechanism where the cable end fits and this is pulled to rev the engine. Have a look and see if there is a cable attached. There may be 2 on yours, one to open the throttle, the other to close it and snap the throttle closed which is aided by a spring. When you open the throttle does this move? Yes, then the cable is doing its job. No, then the cable is not operating properly and is either broken or has come away at the throttle end and will need looking at. With the engine idling try to move the mechanism manually and see if the revs increase and then drop off when you release it (you might need a screwdriver to reach in to do this). If it revs and drops back down as it should, then the mechanism is operating as it should, If it doesn't alter the engine speed despite moving back and forth then it has detached itself in the carb and that will require investigation. At least if the cause is found it could be an easy fix, or cut the mechanics costs by pointing him in the direction of the fault.

What all has to come off, when replacing throttle cable?


need some more info, type and year of bike etc. As a general rule of course the throttle itself has to be opened up to dis engage the cable end, a slow methodical trace of the cable up to the other end will reveal what needs to be moved. Usually the gas tank, if it's a single carb, a slide type; the top of the carb has to come off, to remove the existing cable and re attach the new one. Other types of carbs or fuel injection just runs over a bell crank. Send in some more info.

Carb is sticking.


car and start it up and try to push the gas pedal and it doesn't move. Perhaps it comes free with a bit of coaxing, or force, but, over time, this problem is certain to get worse.Or, far more frightening, you're on the freeway and push the pedal to pass a slow moving truck. When you take your foot off the pedal it doesn't come back up and your car goes speeding down the highway.
Having a sticking gas pedal can be a very dangerous situation and you shouldn't drive your car if you're experiencing these kinds of problems. However, it may be an easy fix once you figure out why it is sticking. The gas pedal to throttle connection is actually quite simple. The pedal acts as a lever that moves the throttle able in and out. The throttle cable pushes a small lever that opens and closes the throttle. Any problems with the gas pedal is certain to be in one of these three parts.
The first step to diagnose the cause of a sticking gas pedal is to remove the breather so you can get to the carburetor or the throttle body on a fuel injected vehicle. Once the breather is removed you will be able to access the cable linkages. Disconnect the cable from the throttle. You can now move the throttle manually to see if the problem is there or if it is in the cable or the pedal.
If the throttle moves freely the issue is most likely somewhere else. If the throttle is the location of the problem you will want to clean that. Depending on whether you have a carbureted or a fuel injected vehicle you will want to make sure you get the appropriate spray cleaner from your parts dealer. Fuel injector cleaner won't get all of the stuff that might be causing problems on a carburetor but carburetor cleaner will leave residues that can damage a fuel

Engine continually has high idle, wont kick down. also the choke light comes on when not pressing on the gas and makes an anoying sound. but only when not pressing the gas. what could this be? other than...


try getting a can of carb cleaner . removing breather and spraying gunk out of the inside of carb to free moving parts that are sticking. and also try spraying the outside moving parts of carb with penetrating oil

Gas pouring out bottom of carb won't ping out


Hi and welcome to FixYa,

Gas pouring out is an overflow. The only reason there would be an overflow is when the float activated valve does not close the fuel inlet port. This could be caused by dirt, sand, rust or any foreign material. Fix would call for a carb pulldown, soaking non-rubber parts, and cleaning.

Good luck and thank you for asking FixYa.

My 84 YZ250 had the throttle lock up - like full throttle with no change by throttle grip - had to turn gas off at shutoff valve to get it to stop - any idea .......... other question - is the throttle...


There should be a small air gap at the bottom between the slide and the venturi. A couple things to check are (we'll start easy and progress from there):

Remove the carb from the air box and the intake boot, but do not remove the top screw cap or cable from the carb. Once you are holding the carb in your hand, twist the throttle and see if the slide moves up and down freely. Does it return to the botton of the venturi on it's own when the throttle is released (or you twist the throttle forward)? If not, and the slide is sticking open, it is allowing more fuel/air in which is the problem. There is a spring under the top cap which should push the slide back down when you release the throttle. If it's sticking open, it's either a broken cable (you wouldn't see the slide go up and down when you twist the throttle if it's broken), or an unlubricated cable, a piece of debris in the carb between the slide and the carb body, or the spring is whacked. Unscrew the top cap, slowly pull the cap, spring, and slide up and check the spring. You can't miss it, it's a big one right under the cap. If it looks ok, check for debris on the side of the slide and in the carb body to see if there is sand/dirt causing the slide to stick open. If all of this checks out ok, then check the cable for free movement when you twist the throttle. If it's sticky, lube the cable. If it's ok, move to the next step.

On the bottom of the slide you will see the jet needle. It's long, skinny and tapers at the bottom. Try moving the needle up and down. It should be pretty snug. If the "c" clip that holds the needle came off, it will sometimes allow the needle to remain open which will cause this problem too. If the needle is ok (in place nice and solid and doesn't move up and down freely), then go to the next step:

Remove the float bowl and check to see if the float, float valve (under the back edge of the float where the float attaches), and seat (where the valve rests in the carb body) are all in good shape. If the float has a hole in it, or the tang holding the valve clip is bent, it will cause the float to drop down lower in the bowl, which opens the valve and allows more fuel in. Also check that the clip that connects the valve to the float did not come loose. If there is a problem with the float or float valve allowing too much fuel into the bowl, the excess fuel runs into the engine (via vacuum when the engine is running) and will cause the problem you are seeing. In this instance though, there is normally excess fuel coming out of the overflow hole on the side of the carb when the bike is not running and the fuel is on. If your problem just happened once and you shut the fuel off (and haven't turned it back on yet), put the float bowl back on, reinstall the carb and try opening the petcock (gas shut off valve). Let it sit for a few hours or overnight with the gas on. If the float or float valve is bad, you should see gas drip out of the overflow on the side of the carb. You may not have seen this if the problem just started happening while the engine was running. It was sucking the excess fuel into the engine causing it to rev wide open. When you shut off the gas flow, it prevented having the excess fuel drip out the overflow hole and letting you know it was a float problem. Hope this helps.

Ryobi cs30 starts fine, but idles way too fast after warm up. I mean screaming fast. Throttle return works fine and idle adjustment is set at it lowest.


you need to take your air filter off and look into the throat of the carbruetor to see if the ""Butterfly""
is still intact and working not the choke butterfly its the one closest to the engine that moves with the throttle and be sure it is still there and moves as you move the throttle.... open is horizontal and closed is not quite 90 Degrees. check to see it is tight and in the center if the throat when closed.
you may have to remove the carb. to see it function more clearly
make sure the throttle cable is free and not binding any where and to be sure of its adjustment to allow the throttle to return to the idle position.
lubricate the cable from the trigger to carb. wd 40 is ok.
if all above is ok then find the L on the carb. and ccw it 1/8 turn to ritchen it alittle to help slow the idle down some to a respectable level
