SOURCE: 93 honda cr 125 r has no power

i bet it is the float needle check to see if it has dropped down to the last notch. i think there are three they regulate the amount of gas that goes to the engine its in the carb and easy to check.just unscrew the top piece and its right there.

SOURCE: 2002 yamaha wolverine 350 4x4 fuel mixture screw

turning the screw way out makes the mixture lean, so the problem must be the carb is too rich.
check all the jets were installed correctly when the carb was cleaned
make sure the carb float bowl is not flooding.
Check the fuel tap is working correctly.
make certain the airfilter is clean.
check the engine has correct amount of clean oil( not fuel contaminated)

Hi, Liz and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.
8. Air/fuel mixture screw set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.

Got spark got gas want fire at all


chances are the carb is not set properly. turn the screw on the carb all the way in then back it out 1 1/4 turns. as a trick you can spray WD40 in the carb to start it too. if you can get Either, that works best. you may need to adjust the screw to get it to run at peak performance. adjust it in 1/4 turn increments.

Kids quad will not start


Install a new spark plug. Remove and clean the air filter. Spray some starting fluid into the carb and try to start the motor. If it doesn't start then remove the carb and clean it;
Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the
carb back together and install the carb. Let the float bowl fill then start the engine.

Quad bike keeps cutting out



ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There may be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Cutting out


I'm not too familiar with Triumphs but assuming your bike has carbs and not fuel injection, then it is time to clean the fuel system. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an in-line fuel filter.

For each carb > Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plugs and start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.

You may want to go to a richer main jet. If the jet is (for example) a 178 then change to a 180 or 182. This should fix the top end problem. Do this only if cleaning the carbs doesn't work.
