Hi i have left side leaking carb after sitting for a while. What would be the issue


I do a lot of small engine repairs, and commonly when the fuel is cut on and the carb starts to leak, your float is stuck open. you said that it has been sitting for a while., How long? Over a period of a couple months, condensation will start to build up in your tank and carb float bowl, with this happening it starts to build up corrosion and electrolysis. To fix this problem :: 1 drain your tanke completely. 2 remove the carb float bowl from one or both carbs ( however many your bike has) ((DON'T LOSE THE GASKET) 3 carefully remove the pin holding the float in, and when you remove it be careful, there is another little pin with a rubber tip attached to the float 4 clean them thoroughly, pins and float, 5 clean inside float housing 6 Reassemble, carefully in exact order you took it apart. 7 fill tank with fresh gas and add 2 ounces of STABIL water remover and fuel treatment. This should fix your problem.. Let me know how it goes

I have a 1981 yahama 850 midnight special. It has been sitting for 3 years. I tore apart the carbs and cleaned them. After putting everything back together the middle carb is leaking gas out of the two...


Is it poss to remove the float bowl while the carbs are fitted to the bike? I am fairly sure back in the eightys the float was addjustable, to controll the fuel level by bending slightly the metal tab on the float, when the bowl is removed check the level of fuel in the bowl and compare it to that in the others, the aim is to make the fuel flow stop at the correct level in the carb(by bending the float tab) while the bowl is off turn on the fuel push the float all the way up check if the fuel flow stops, also check the condition of the sealing washer around the float needle seating.

The bike wont start up. it has a spark and has good compresion. what could it be.


It could be timing or fuel.Your next move is to make sure your getting gas.try to start bike with throttle wide open.Stop and remove spark plug,is it wet,if yes your getting fuel.If dry your not.If dry your next move is to remove fuel line from carb,while removed turn on gas valve and see if gas flows.if this is good then there is no problem with a tank or fuel valve blockage.Now you must remove carb and diassemble(carefully)as not to loose springs and float valve assembly.remove float bowl screws on bottom of carband slowly drop bowl down away from carb base.check for dirt in bowl.make sure floats move freely.what I am getting at here is if floats are stuck in up position this keeps gas from getting to motor.If you want to disassemble floats to get to needle valve you need to carefully remove pin holding floats in place lower floats paying attention to needle thats attached to float base.there is a spring or clip that holds this in place so take a close look before you take apart,because it must go back togather the same exact way it came apart all you need is a grain of sand inside needle valve for the float to stick and no fuel will get through.The reason i am telling you all this is because this is a common problem when bikes sit over winter and get sediment in bottom of gas tank.Good luck and let me know how you make out....Brian

Try replacing spark plug,and check for spark if you do good,check to see if you have fuel to carb,at bottom of carb there is a float bowl screw loosen the screw and let fuel drain,tighten screw,choke and try again,sometimes when bike sits that long it may need one or two cleans,the bad gas that was in it still has varnash build up and can still clog up the jets.hope this helps.

I have a ttr 230 with twenty hours on it. It was hard to start the other day and will NOT start today. I took carb off and drained it, checked for debris and looked at the float and it seemed fine (there...


Gas running out the puke tube indicates debris in the float valve(Stuck Float)
some just tap the side of the carb and it passes through, some take the carb apart, clean it and reassemble it.

In your case, remove the carb, remove the bowl from the carb., remove the float pin, then the float, and the float valve/needle is hanging on the float tab.

now blow through the tube that the gas line hooks to with compress air to clean out that passage.
air should blow out the hole that the float valve was in.

Reassemble.

You will not have to remove any jets to clean the float bowl chamber.

i suggest you blow through every opening on that carb while you have it off to make sure nothing is clogged.

Your float will now shut off the gas flow like it should, and quit coming out the puke tube.

Dirt bike turn over but wont stay running


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 ). Fill the tank and use only premium gas.

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. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to 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.

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

Gas pours out of bike when I turn the key


Sounds like one really crappy and dumb dealer if you ask me. Yes, they usually have gas in the tank on the showroom floor. Yes, varnish can build up while on the floor. The good thing is that cleaning a carb is not very hard.

Carb help


I'm new to the site and new to carbs. I bought a bike last week that had been sitting in a barn for a couple years the engine hadn't been running in over a year. I was able to get it running the first day after cleaning out the field mouse home occupying the air filter chamber and swapping the old gas for new gas. The bike ran and idled fine but the left carb (dual carb setup Keihin) poured gas from the tube coming out the bottom. I did some research and found out the floats may be stuck. I went ahead and ordered new floats and float bowl gaskets. I took the carbs apart apart as much as I could, using Berryman parts cleaner to soak all the metal parts I could get off. I put everything back together and put the new floats in yesterday. I started the engine and not only is the gas is still pouring out the bottom of the left carb, but now the bike is idleing very fast. The idle adjustment is backed out completely. When putting the carbs back together, I screwed all the jets back in all the way. I screwed in the Pilot Air screw, the one with the spring, all the way in, then backed it out 1 1/2 turns. Not sure if this has anything to do with the idle. As far as the floats go, does it sound like I need to replace the float valves too? ,The seats on the jets, or the o-rings on the needle valves that the floats control are probably leaking.,,,
