SOURCE: fuel pipes te610 husqvarna

the tank thumbscrew on the left side is you reserve. it needs to connect to the petcock on the right side, across the carb to the top pipe. the petcock should have arrows on it (backside). the bottom petcock pipe goes to the carb. the carbs inlet pipe is on the right side and is adjustable...single screw in the center of inlet pipe allowing it to be rotated for straighter hose connection. that is depending on year of coarse.

SOURCE: When trying to start fuel pours from the carby

Been there done that, Carb needle stuck in the open position. Do NOT try to start it this way as if a cylinder fills with fuel it will hydrolock and cranking the engine can break expensive things. If you need to crank it pull the 3 spark plugs on the effected side and crank it over to remove the fuel from the flooded cylinders. This may require carb. removal and tear down if tapping on the carb bowls doesn't fix it. Same thing happened to my 1999 Valk. Interstate.

It sounds like the engine is not getting enough fuel for it to run. First check that you have the fuel tap in the on position. If the fuel tap is on then the carby might be blocked or the needle & seat are not working properly. Turn the fuel tap off. Then take the fuel bowl off. You will then see a plastic float,turn fuel tap on. Fuel then should be flowing from carby. Push the float up and this should stop the fuel from running. Do this a couple of times to ensure that it is working correctly. If all is good after that then turn fuel tap off. Put fuel bowl back on, turn fuel tap on and test. If no luck, turn fuel tap off. Then you will need to take the carby off the motor and clean it using carby cleaner. Be sure to spray cleaner in all holes of carby and blow out carefully with air compressor. Put carby back onto motor and turn fuel tap on and test.

Seems to be dumping to much fuel. leaking out of number 2 pipe. and from drain tubes.

Sounds like a stuck float valve in the carby. Try tapping the carby float bowl gently with a screwdriver handle. If this dosnt fix the problem, the the carby must be removed and opened up for inspection.

Fuel is leaking from the carb into the cylinder and airbox when bike left overnight. Changed the jets but problem still there

You should adopt the habit of turning the fuel tap off when not riding, this will isolate the gravity pressure from the fuel in the tank.

The jets control fuel flow when engine is running,

I would think your float needle and seat is worn in one or more carby's. try a spray through of carby cleaner by turning fuel tap off and taking fuel drain screws out of all 4 carby's, disconnect fuel hose from fuel tap, allowing fuel to drain from lines and carby's. Spray carby cleaner into fuel hose and allow to flow out through all four carby's, allow to drain fully and dry out. Replace drains and fuel line and let fuel flow to carby's and see if a spray clean has done the job.

If not, inspect each floatbowl needle and seat. The link below gives exploded views of the bike in sections, with part names to help you get to them. Cheers.

The vent hose usualy goes down past the swing arm and is open to the world. the fule outlet suppies flue to the carbies and the vac tap one come from a vac port/s on the top of 1 or 2 carbies. and the other end goes tot he back of the fuel tap to turn it on.

Fuel coming (sometimes pouring) out of the airbox vent pipe when the engine is turned off. It will also continue for a time with the ignition off and then slow to a stop. But will sometimes start again...

Sounds like needle & seat in carbys could be sticking or float levels maybe to high when you turn your key on your fuel pump starts and this puts pressure on needle & seat and if floats are to high the petrol just keeps flowing Float is what stops petrol flooding the carbies, check minor things first like dirt in needle seat if you have a compressor give carbies a light blow out.

I have 2 extra small pipes coming off of the fuel tap and i dont no what they are.can you please tell me what they are for.for my nc24 vfr 400 honda.

A fuel tap normally has 3 pipes, 2 in and 1 out. If you have a fuel tap they you have a manual reserve. The first pipe will be linked to a long tube (main fuel supply) the second will be linked to the "reserve. It is all in the same tank space. When the fuel gets low the main pipe will **** air and the bike will starve fuel. Switch to the reserve and you will be drawing from the lower pipe (reserve, ie start looking for a fuel station) It is not recommended to use the reserve as the fuel in your tank normally has sediment at the bottom and blocks your filters. This sediment comes from the tank rusting and from the fuel pumps drawing bits from the concrete fuel tanks at the fuel stations.

If you strip the tap you will be able to see which is the main and which is the reserve.
Hope this helps

1994 ltf3004wd king quad fuel pump connections,not sure what outlets are what,winds over wont start,not really getting fuel to carby,have good spark,compression average,did go before though.

There are three connections to the fuel pump.
Fuel in/out at ends, the pipes should only reach to the correct ends. The IN pipe connects to the end toward front of the bike , OUT toward the back heading to carb.
A small connection on the back for the vacuum pipe from the carb.

This pump only spits the fuel along rather feabley, also check the gause on the fuel tap. When bleeding, remove the fuel pipe from the carb and blow into the tank in order to force the fuel through the pipes until all air is removed.

CBX550 carburettor vacuum system

Hi Simon,
Fuel over flowing from the carburators/over flow pipe means the float pins are not sealing off.
You will have to remove the carbs and the float bowls to check the pins and will have to adjust the floats too .
The vaccum fuel tap runs or rather allows fuel to pass by once the engine is running (thus creating vaccum) if you check around the inlate or the carburator mountings, in one of it you will find where to plug in tht pipe.
Hope this helps!

Fuel starving at cruising speed 100kmph

it sounds like you guessed right,the fuel tap is not correct for that bike,i had one in then shop the other day and it is two pipes coming off the fuel tap 1 to each pair of carbs,by changing to a single pipe of the same diameter you are effectively cutting your fuel supply in half and every "t" fitting that goes in the line restricts it further...go back to the standard tap fitting and get rid of all the "t" fittings and your problem should go away
