Honda falcon nx4 gas leak from carburator when I turn the valve on, only when it is parked

While it COULD be the float level is set too high, if you haven't had the float bowl off, more likely it's some crud in the fuel got stuck between the float shut off needle and it's valve seat.
This doesn't allow the float needle to shut off completely, and fuel will keep coming into the float bowl, even though it's already full.
This is more pronounced with the engine shut off, and sometimes at idle, and less so as the engine revs increase.
This is because the faster the engine is running, it's burning more fuel, and better able to keep up with the overflow.

A) I didn't know Yamaha makes a Desktop PC.

B) So far, I don't know of any desktop computers that use an internal combustion engine, and use a fossil fuel to run it.
Hope not because this is going against the grand scheme of things, lol!

C) Fresh top end, and a carburetor fuel induction system; plus flooding out?

1) Float level is set too high.
Readjust level. Worked fine before top end job?
Maybe it got bumped.......umm, like dropped.

Carb was rebuilt too? Float level is not correct.

2) The tip of the float needle is Neoprene. As such it can be damaged from a fall.
It can also be deformed from having too much pressure applied to it, when installing.

3) Float needle seat has come loose from carb main body.

4) Float needle seat is damaged. Tightened too tight, etc.

5) Junk in fuel tank has made it's way into between float needle, and float needle seat.

6) Float needle hair spring clip, was not properly installed on float.
(If used)

7) Carb was Not rebuilt, has sat while top end was done. This took some time, like weeks, months, to get too.
All the cr@ppy additives in the gasoline, has collected in the float bowl; and causing float needle to not set correctly in float needle seat.


(Now watch. You'll come back with a voice like Stimpy, and state;

"joecoolvette, you stink-ing idio-t!
I was referring to my Yamaha desktop computer. It's spraying gas out of the carburator. You have no idea of what you're doing.

Signed, Stimpy)

What is it when I am going up hill and step on the gas the truck starts cutting out?

Inside your carburator is a mini gas tank (float bowl) that keeps a specific amount of gas in reserve to accommodate changes. It isn't getting enough gas. The most likely culprit would be the fuel filter, so get it changed first. If that doesn't make the problem go away then the fuel pump is likely getting weak and not pushing enough gas into the carb. You can get it tested before you change it to make sure. If it tests good or you change it and still have the problem you will have to get the carburator taken off and rebuilt. Over time there will be a certain amount of crud acumulate in the float bowl that is interfering with gas delivery or it's also possible the float has become "waterlogged" and is not keeping gas at the proper level. Rebuilding carburators is not a job for rookies. It may cost more up front to have it done by a shop, but it will save you a lot of grief in the end.Hope this helps.

When I start my pressure washer on full choke it works fine when I place choke in wide open position gas runs out of the carburetor.what could be wrong.the engine issas by Briggs and Stratton.

You need to take the float bowl off the carb from the bottom . You haven't given a lot of information about who did what to the carburator but somebody must have screwed with the float pisition for this to be happening . The way all carburtors work is the same you have the float bowl and the floats and on top of the floats is a valve called the needle valve. Now the neddle valve is there to stop the flow of fuel into the float bowl when the engine is not in a high damand cycle for fuel like start up or ideal the choke shuts the air off and gives more fuel at start up .However when the engine is running and the float bowl is being filled by gravity feed from the gas tank the floats will move up do to the amount of fuel in the float bowl and should shut the fuel from the gas tank off to the float bowl until the engine can burn the fuel and drop the float level enough to make the neddle valve open again to supply more fuel for the engine to run correctly its a never ending cycle . You need to adjust the floats and likely clean the carburator don't mess with adjustments there mostly automatic when the engine is running

I need to know the correct carburetor float level for a 2005 ktm 65 sx

All carburators work axcitly the same . The float level is dertermined by the amount of fuel in the float bowl . When the fuel level reaches a point in the bowl the floats rise and shut of the neddle valve until the engine can draw enough fuel out of the bowl to drop the floats so the neddle valve opens again to supply the bowl with fuel to make the engine run its fool proof . If your haveing an over flow issue where fuel is running out the tube on the sides then pull the carb and clean it you shouldn;t need any parts just a can of carb cleaner and always clean the air filter that how dirt gets in .Good luck with it

My TZR 250 3ma, leaks fuel from the carburators, I had them cleaned and the float levels resetted. On the fuel tap if it is on or on reserve it gushes out the fuel. Can the tap be the problem and is there...

The tap is not the problem, it is working as it should. The problem is that the float needles are not shutting off the fuel as they should. Turn the gas off then remove the float bowl on one carb and check for trash in the bowl. Turn the gas back on while gently lifting the float. Now lower the float. The fuel should flow when the float is lowered and stop flowing when the float is raised. If it still flows with the float raised, turn of the gas then check to see if the mechanic forgot to install the float needle by removing the pin that mounts the float/needle assembly. Most carbs attach the float tang to the needle with a small clip. Is the clip missing? The needle can get out of position and not close properly without it. The float should be light as a feather and nothing inside rattling around. A float that doesn't float will never shut off the gas. If the float is good, disconnect the gas line at the carb then get a can of carb cleaner with a "straw" to direct the spray and stick the straw into the opening where the needle goes and spray into the hole. Trash may be holding the needle open. The spray should clear the trash out. If the float floats and there is no trash holding the float open and the needle kills the gas, the floats are way out of adjustment. Below is a generic float assembly. Please take a moment and rate my answer. Thanks! tombones49_45.gif

Sir's, I have 8HP Briggs & Stratton Synchro


The main cause for your problem is a carburetor, the needle valve is not fully closing on the seat. This allows fuel to keep entering and overflowing out of the float bowl. The fuel only overflows when the tractor is not running. While it is sitting the fuel travels down the intake, and most of the time the intake valve stops partialy open and the fuel enters the cylinder. The fuel sits on the piston and slowly migrates past the piston rings and enters the crankcase. After a period of time, the oil level rises and then gets pumped up and out the breather tube.

If you trailer this piece of equipment, you might consider useing a fuel shut off. The bouncing causes the float to open and close, thus causing the same effect.

Hope this helps, Matt

Rebuilt carburator and truck runs rich. Cant get adjusted right and under accelereation truck boggs down

im pretty sure that the float adjustment is set wrong, if to high it will act as if truck is flooding out, and be very rich. if to low you will not get the power you need. readjust float level. make sure there is no dirt inside carburator. for adjustment turn screws way in and back out 1 and a half turns.start from there.

set the fuel level to about 3MM below the gasket surface. I have syncronized them so they are all right together. They all read 8 inches. It idles great but when I snap the throttle it will stumble and if I really open it the engine will stall. I noticed quite a bit of gasoline being blown backwards from the carbs. Is this normal. I have seen this with 2 cycle engines, but don't know if it is normal for a 4 cycle. I have also set the points and ignition timing. I did set the fuel level consideralby higher then the manual said. It said to set the float about 1 inch, and I set them about .675 or something like that, but what I was after was the fuel level in the bowl. It acts like a lean situation, so I raised the metering rods two notches. Could I actually be causing a flooding situation, or is it still to lean? Oh, I did a compression check, all were right around 135psi. ,you need to set the float level to the factory specifications.if i understand your post you have increased the fuel level height in the bowl by 3/8 of an inch and raised the needles also.the only possible result of this is too much fuel.,,,
