Chk your tank and lines for trash blockage, when you get fuel to the carb go from there, the overflowing is caused by the needle valve in the carb sticking open, usually caused by trash in the fuel, make sure you are getting fire to the plug as well, I know for a fact the wiring systems on these things are not quality systems.

Cleaning the fuel float bowl

Note: this procedure will often cure no start issues and or surging issues, or once done a little running after the fact will clear up surging issues as well.

Often gas with ethanol will cause gunk build up in the float bowl making your mower run badly and have a 'surging' behavior especially at low idle speeds, or cause it to not run at all (almost all gas has ethanol as an additive now for 'emission' reasons so assume you have it unless you KNOW you don't). This can take as little as a few weeks or a month or two of not running to happen. Frequently a simple float bowl and carb cleaning will resolve these issues completely or at least to get you back to a running point.

To clean the float bowl area, it's best to remove the carb. (make sure you pinch off gas lines with a vice grip or similar to keep it from spilling out and remove things carefully to avoid breaking seals on the intake)

Tip the carb over a catch basin or oil drip pan and turn it this way and that to pour as much excess fuel as you can. If your carb has a electric solenoid or an overflow screw on the bottom, removing this will let you pour fuel out of the bowl area.

To begin cleaning, Turn the carb upside down. Typically there are 2 or 3 screws that hold the bowl to the bottom of the carb. Do ALL of this over a nice metal tray that will catch any falling parts like small screws, carb jets, springs, plungers, etc.

Very carefully undo these screws and work the bowl until it breaks free of the seal

gently pull the bowl off the bottom of the carb. and you should see the float mechanism and main jet sticking out toward you. This visible area, all the orifices, and the bowl you removed are what you want to clean.

ANY orangish discoloration, sediment, or other gunk that is not obvious parts of the carb is bad news.. or good news because you're about to remove it and you found a problem that was worth fixing. If everything is clean, shiny, and aluminum and plastic looking, all is well in there, put it back together and move on to other DIY projects. :)

To clean it out assuming you saw at least a little orangish discoloration, a good pressurized can of carb cleaning spray is GREAT... HOWEVER, do not let carb cleaning spray get on ANY gaskets or rubber seals. The chemicals in carb cleaner will expand the rubber and make the seals not fit properly anymore and ruin them. (beware there is a TINY, impossible to see rubber seal on the plunger for the float so you MUST REMOVE THE FLOAT if you want to use carb spray to spray the metal on the carb or the jets while they are still on the carb. It may be better to just use a little gas in a metal tray and a soft toothbrush to scrub things off and clean them out. Typically it's just a pin you have to slide out in order to remove the float and plunger, it's sometimes a little tricky getting it back in just right.

You can also use your air compressor spray tool to blow out passages and dry out parts you are cleaning and it's great to blow out all the orifices you see in both directions ... BUT ... watch out because it is easy to accidentally blow out the jets and lose them! Also, wear eye protection ... seriously, do it, even if you're not using compressed air.

Once you have cleaned everything, make sure no little parts are in that handy metal tray you worked over the whole time. If there are any, find where they belong and put them back. Nothing in there is unnecessary... nothing!

Once you put it all back together, the carb will naturally refill with fuel and you should be able to start right up after a few seconds of cranking.

Any residual surging will often clear up after some run time, I like to use a little mix in gas carb cleaner after doing a carb cleaning. If my tractor has sat more than 2 months not running, I often check this before even trying to start to make sure I don't pull any gunk that did build up into the jets and clog them. Cleaning the bowl is easier than cleaning the orifices!

1980 750 honda carbs leak gas from bowls

Most likely, one or more of your carb floats has gotten stuck. The carbs have connected, so one sticky float will impact all the carbs equally. With the bike on the center stand, you can turn on the fuel petcock and see which bowl starts overflowing first, but that's not a perfect test.

The right way to correct this is to dismount the carbs and clean out the bowls and floats to ensure that everything is working properly. This would also fix the issue of having some dirt in the needle valve, preventing it from fully shutting off.

The sloppier fix that might or might not work for you is to leave the carbs in place and drop the bowls for the outer two carbs. When a bike is routinely parked on its side stand, I've found that the right hand carb, which has the lowest gas level and hence is a bit more likely to gum up. A dose of industrial strength carb cleaner (I like the stuff labeled "gum cutter") may free everything up--though you have to be careful that you don't damage or dissolve plastic/styrofoam floats.

Good luck!

I have a 06 honda trx250ex put new gas and oil in it and plug and battery and iit turns over but wont start but when i put started fluid in where the plug goes it starts for like a second or so and quits...

your problem is a clogged carb. clean float valve, main jet and idle circuit with a can of spray carb cleaner.

disconnect fuel hose at carb and see if gas flows.

reconnect hose and open float bowl drain valve. If no gas tap on side of float bowl with plastic end of screwdirver to free up float.

still no gas? remove float bowl and try to shoot carb cleaner into the fitting for the gas line from tank.

if gas flows now then put it all back together and it should run

if not then remove carb and clean carb passages, main jet, idle circuit.

Carb leakes gas out overflow

It doesn't take much to hang the float valve open. The smallest speck of dirt or debris will cause the float valve to not shut the flow of gasoline off. After sitting for that length of time, the carburetor needs to be completely disassembled and cleaned. Use an automotive carburetor cleaner (but do not put any plastic or rubber parts in the carb cleaning solution as they will be eaten up). While you've got the carb apart, inspect the float valve. Replace it if there's a groove worn into the tapered seat. Installing an in-line fuel filter may help, too.

I have a 99 yamaha r1 and it spits gas out of the over flow tube how do i fix it

clean the carbs, you have a sticky float allowing too much gas into the chamber thus overflowing.
remove air cleaner and box, whatever you need to do to get to carbs, get a good spray cleaner and get a load in them, put it back together but leave bike to sit overnight try starting after 24 hours

I think you are saying that when the gas valve is turned on, gas flows out of the carburetor and onto the ground. If that is correct then the float valve in the carb is stuck. This is not a big thing to fix.

Take the carb off the motor and turn it upside down. You will be removing four parts so be sure to put them back in the same positions they were when removed.
Remove the float bowl at the bottom of the carb.Inside there will be a float. There is a little "float needle" under the flat tang of the float. This needle has some trash in the seat that will not let the needle close properly. Remove the long pin that holds the float in place then set the float aside along with the needle. Now 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. Now put the carb back together and install it on the bike.

This should fix the problem.
