    1986 Honda CT110, I have the service manual, and go to the troubleshooting section, but see no solution to the engine running good as long as the choke is fully on.

  • Rodger D. Lewis Feb 07, 2010

    Is there any product, as a gas additive, that can be used to help clean out the fuel lines and carbuertor while the bike is running? Just took the bike, honda ct 110, for a ride and all was good, except still cannot turn off the choke, really don't want to pull the carb again if I don't have to. Thanks for all your help

Hi, when an engine runs well with the choke closed, this allows the choke to restrict air into the venturi of the carb. I know you soaked all the parts, but was compressed air used to blow thru all the ports? At this point, it seems your high speed idle passage is restricted, resulting in not enough fuel entering the engine. Another point may also be that the float may be out of adjustment. I mention the previous with the assumption that the spark plug is not fouled and proper fuel flow is reaching the carb and the o-ring/gasket that is located on the mounting flange is good. If you find that now matter what you try to do will not correct this carb issue, a new carb is available for about $35.00. Thanks.

    You can try adding a liquid fuel injection cleaner to the fuel. I must say, this may or may not correct the problem, but it won't hurt to try.

How come my troy snowblower stalls when I move the choke switch from choke to run ?


Most likely issue is dirty carburetor. Dissasemble and clean with carb cleaner or sea foam (let parts soak in it, if possible), reassemble. Could also be head gasket, but less likely.

LA110 only runs with choke


Most likely the Nikki carburetor needing a good ultrasonic cleaning and a carburetor repair installed. It would be best for regular lawnmower repair shop to do this as the Nikki can a pain to get the parts replaced correctly and even the new gaskets can leak sometimes.

Primer bulb will not prime


Hello Tony Galvan, I had to replace the fuel lines to keep from sucking air when I pressed on the primer bulb. Also, I took the carburetor apart and found the gasket was good by holding it up to the sunlight, no light came through indicating holes in the gasket. Then I took a magnifying glass and looked at the bottom half of the carburetor and noticed that a soft film of what looks like lint from a dryer had accumulated on a screen mesh type of filter. Once I cleaned the debris away, the weed wacker started every time. I pulled with a full choke and partially wants to start. Then moved the choke to half choke and pressed on the throttle fully and pulled, it started! But you must at least hold the throttle close to full until 10 seconds for the engine to warm up. Then move the choke to idle. Hope this helps.

Hello
You may have a clogged main jet in the carburetor, remove the engine shroud to expose the carburetor, the carburetor will be held on in most cases by tow bolts and then a basket underneath, remove the carburetor and flip it over in a rag to catch the fuel, then remove the screws holding the fuel float bowl on, carefully work the bowl loose to avoid tearing the bowl gasket, if you do damage it you will need a carburetor repair kit. Once the float bowl is removed remove the floor and the needle valve at the fuel inlet, set them aside, using a can of spray carburetor cleaner spray the inside of the carb and then blow through the jets with compressed air to dislodge the dirt (this is a must) that is obstructing fuel flow and causing the lean stall out, reverse and reinstall you should be good to go.

My Stihl whipper snipper will not run after I have started it with the choke then turn choke off. What could be the most logical explanation and remedy? Cheers John


Hello,
My name is Dane and I am going to assist you in solving your problem.

If your fuel is mixed with oil, make sure it is mixed correctly. Too much oil in the mix will cause problems. Make sure you haven't left old fuel in it for a long period of time and gummed those jets up. Sometimes an engine just needs to run with good fuel in order to clean the jets out. If this is the case, just replace the fuel, get it running and work it normal for a tank of fuel if you can. You should see improvement by then.

If it still doesn't run correctly, you will have to adjust or clean the Carburetor. If you need to clean the Carburetor, you will probably need to remove, disassemble, soak, and use compressed air to blow out the jets in your carburetor. Pay close attention to how the carburetor is attached to the engine. Make a drawing if you need to or take some pictures. Remove the Carburetor from the engine. Remove the air filter, linkages, throttle/choke cables and fuel line. Remove the mounting bolts/nuts. You will need to disassemble the carburetor as far as possible and put it in some Carburetor cleaning solution. You can get this at any auto parts store. Do not place rubber parts in the solution. Allow it to soak in cleaner as directed, and then blow out the ports and jets with compressed air immediately after you take it out of the cleaning solution. Be careful not to get any spray back on your skin or in your eyes. Reinstall the Carburetor in the reverse order. Replace any worn or torn gaskets or o-rings as you assemble and reinstall it.

If you need to adjust the high-speed mixture setting on your Carburetor, turning the screw out just 1/2 turn or so should do the trick. It is not so hard to adjust the Carburetor, however you do need a special tool that is very hard to get your hands on. They don't make many engines with plain screw heads on the jet screws anymore. The newer Carburetors are factory set lean so they can pass emission standards. If you have a local dealer, they should adjust the mixture for a couple of bucks. If you can adjust the screw, start the engine, allow it to warm up, and apply full throttle. Start backing off the screw just until the engine gets max RPM. That's it. You're done.

Just a TIP: Always mix your fuel with an approved fuel stabilizer. Fuel begins to go bad after a few months and that's why many people have fuel problems in the spring.

I hope I've helped. Thank you! Dane

Ct110 honda will not stay running with out the choke fully on, and suggestions Please


Disassemble the carb and clean it. Soak the parts in denatured alcohol for 30 minutes. Home Depot and any hardware store has it. Now use spray carb cleaner from the auto parts store to finish the cleaning. Be sure to spray into all the little holes (fuel circuits) and into the throttle and air screw holes as well. Put both the throttle and air screws back where they came from and screw them in until they LIGHTLY seat. Now turn each of them outward one and one half turns. This is the factory setting. Also clean the air filter and install a new spark plug ( NGK DR8ES-L ). Check the rubber O-rings on the intake manifold and replace them if hard, cracked, cut or abraded. You can order the parts from www.babbittsonline.com/parts/viewbybrand/parts.aspx This site will show an exploded view of the entire motorcycle. Please rate my answer. Thanks.

Cannot keep tiller running


Could a gas/oil mix been used by mistake. When you cleaned carb did you also clean dusty air filter?? Try leaveing off filter first and run. Are you sure you are in "choke position" when engines seems to be running ok,be sure to double check yourself here. If engine runs ecelleant in "choke" sounds like your in "Run" position and positioning is problem not performance.

Please rate. Thanks jj505
