Laser 72D Fuel Sump

My Laser 72D runs out of fuel. There seems to be a magnet inside the float bowl that holds the float up, in the off position. If I push the reset button each time I hear the pump sucking air it will continue to run fine,otherwise it will run out of fuel and reset. What is the purpose of the magnet and what is supposed to make the float drop?

    It turned out to be an improperly set float. After adjusting it the system works fine. Thank You for the input.

    I have a similar problem with a Toyo Laser 56. However, fuel never gets to the burner pot although it "sounds" like the fuel pump is working. The sump never fills enough to draw the float up and close the intake. It's a relatively new sump (one year) and not that old of a pump (four years).

If your fuel sump keeps tripping, you have one of two problems, a defective seal on the inlet, or your fuel pressure is too high. If it is the latter, then you need to put a pressure regulator inline before the brass connector/flare fitting in the back. If it is a bad seal, which it could also be as the heater you have is rather old, you then will need to replace the fuel sump only.

My 1987 Suzuki 250 quad racer will not crank it keeps flooding out and keeps failing my plug out It will not hit at all


Sounds like the float in the carburetor is stuck. Its inside the bottom of the carburetor inside the bowl. The bowl is just the bottom cover of the carburetor..its an empty bowl shaped bottom that fills with fuel...controlled by position of float that works essentially like a fishing bobber. Remove bowl and press the float up and down it should move freely. If there is any resistance or float does not drop down with bowl removed. The pin that holds the float in place needs to be removed and cleaned. I would also wire brush out the bowl and spray it, the float and float pin with carburetor cleaner. You do not need to disassemble the rest of the carburetor to check and clean the float. In the picture the float is #2, float pin #12, I think there are four bolts #14 that hold the bowl on.

Engine runs for short time then cuts off homelight 2700 psi power washer


There are 2 different enigines on these depending upong your actual unit model number.
One had a Subaru 175 cc engine and the other was a Honda engine. For carb specifics I need the ENGINE model number. Either way... here is what you need to do:
1. Fuel selector off.
2. Remove main fuel line from the carb.
3. Use a spray can lid and check FLOW. It should fill the lid in under 8 seconds. (Feul selector OFF now) If you do not have good fuel flow here you need to inspect the tank exit port, in line fuel filter if used and the sediment bulb under the fuel selector for debris
(GOOD FUEL FLOW NOW)
4. Remove the float bowl by unscrewing the bowl nut from the bottom of the carb. NOTE positon of gaskets as you remove float bowl. Use carb cleaner and direct a spray hopefully with mini extension tube of the carb nozzle into the center of the threaded area of the bowl nut. (This cleans main fuel jet orifice / pin hole) Then spray carb cleaner using mini nozzle extension up the flat side of the float needle until carb cleaner exits the main fuel line connection. Last spray from the main fuel line connection to the float needle (reversed spray)

This usually removes any debris from the float bowl. main fuel jet and main fuel manifold Reinstall the main fuel line.
- Turn on the fuel selector and use the spray paint can lid under the float to catch fuel. It should fill in 8 to 10 seconds to the point your worried about over-flow.
- GENTLY lift the float needle to the level position. FUEL MUST STOP.
- Lower Float to resting position. FUEL MUST FLOW so that it would fill the spray paint can lid in 8 to 10 seconds. (FUEL SLECTOR OFF)

Clean the bowl nut and reinstall the float bowl. Turn on the fuel.. wait 30 seconds for the float bowl to fill completely and start unit. If it runs GREAT... If it only runs with the choke on you still have a fuel supply problem...i.e most likely the main fuel just in the threaded area of the bowl nut is still clogged. .

This should get you going. Thanks for choosing FixYa,
Kelly

Mower will start and run for less than 30seconds before stopping.This is happening with a mower that has been used only 3 times.Air filter is clean and thegas is fresh.Any ideas?


Check that you haven't the throttle control in the start position. Some mowers have a position on the control which turns on the choke and you have to move the lever to the run position for normal use.
Check the spark plug cable is pushed fully onto the plug. The float valve in the float bowl may not be allowing fuel to flow freely into the bowl. Remove the bowl while holding a container underneath it to collect the fuel. The float bowl works like a toilet cistern and the flow stops when the float rises upwards on the fuel in the bowl. Check the fuel is running ok.

My 2006 klx 250 won't fire, no fuel in float bowl, Tank is full, I drained the float bowl to try to get it to start and now no fuel is getting to the bowl


Check the filter screen on the fuel tap for blockage etc. Also check the tap for anything that may have lodged in it and blocking it. Check the fuel pipe too.

Fuel is consistantly running out of the (green) drain line at the bottom of the carburator. The bike seems to be running fine, but there must be a valve stuck open. Can anyone tell me how to resolve? ...


THIS IS THE FUEL LINE USED FOR DRAINING THE CARBURETTOR ALSO, MAKE SURE THE SCREW USED FOR DRAINING THE FLOAT CHAMBER IS CLOSED FULLY, IT MAY BE THAT THE FLOAT NEEDLE IS STICKING, OR IT HAS SOME DIRT STOPING IT CLOSING FULLY, TURN OF THE FUEL, REMOVE CARBURETOR, HOLDING IT IN AN UPRITE POSITION CAERFULLY REMOVE THE SCREWS FROM THE FLOAT BOWL, THEN REMOVE FLOAT CHAMBER,(BOWL) ONCE REMOVED MEASURE THE AMOUNT OF FUEL IN THE BOWL, IF THE LEVEL IS CLOSE TO THE TOP OF THE BOWL, WITHOUT THE FLOAT IN IT, OBVIOUSLY WHEN YOU PUT THE FLOAT BACK IN THE FUEL WILL OVERFLOW, IN THE CENTRE OF THE BOWL YOU WILL SEE A BRASS LEVEL PIPE, THIS ALOWS THE FUEL TO PASS OUT OF THE PIPE IN A SITUATION LIKE YOURS, TURN THE CARB UPSIDE DOWN YOU WILL NOW SEE THE FLOAT ASSEMBLY SECURED TO THE BODY WITH A PUSH PIN, YOU WILL HAVE TO REMOVE THIS TO REMOVE THE FLOAT, WHEN YOU HAVE DONE THIS,, CAERFULLY LIFT UP THE FLOAT,YOU WILL SEE A SMALL VALVE WHICH LOCATES IN THE FLOAT, THIS WILL FALL OUT WHEN YOU LIFT UP THE FLOAT SO CARE IS REQUIRED NOT TO LOOSE IT AND NOTE DIRECTION OF FITMENT, I ADVISE WORKING ON A CLEAN BENCH SO ANY PARTS WHICH MAY FALL OUT CAN BE READILY FOUND , ONCE REMOVED CHECK IN THE VALVE SEATING FOR DIRT ETC, ALSO THE VALVE END MAY BE WORN, WEAR TO THE END OF THE VALVE CAN ALSO CAUSE FUEL TO FLOW OUT OF THE DRAIN PIPE, ONCE YOU ARE SURE ALL IS OK REASEMBLE FHE FLOAT AND NEEDLE ASSY IN REVERSE CHECKING THE NEEDLE LOCATES CORRECTLY WITH THE FLOAT, IF YOUR FLOAT HAS A METAL TAB IN CONTACT WITH THE FLOAT NEEDLE, IT IS POSSIBLE TO ADJUST THE FLOAT HEIGHT IF REQUIRED, I WOULD SUGGEST FIRMLY HOLDING ON THE BOWL OF THE CARB ,AND CONECTING IT TO THE FUEL LINE WITHOUT THE SCREWS, TO CHECK IF YOUR PROBLEM STILL EXSISTS BEFORE YOU RE FIT THE CARB, THEN TURN OF THE FUEL REMOVE THE PIPE AND RECHECK THE LEVEL OF FUEL IN THE CHAMBER IN COMPARISON TO THE OVERFLOW PIPE IT WANTS TO BE AT LEAST 5MM BELOW THE TOP OF THE PIPE, SOME BOWLS HAVE A LEVEL LINE IN THEM, CHECK IT OUT GOOD LUCK, LEVEL OF DIFFICULTY ONECE CARB IS REMOVED, 6 BASED ON A 1, TO 10 SCALE

I have a Coleman Powermate 4000 watt generator. Gas is leaking from the bottom of the carburetor. What is wrong?


Hello Pete,

Is fuel actually leaking from the bottom of the bowl, or is leaking out the air filter and running down to the bowl?

If the former, then your bowl bolt's gasket has likely deteriorated. This would allow fuel to run down the bolt itself. Note that some carburetors will have a fuel shutoff solenoid (to the engine, not to the carburetor) that holds the bowl on, rather than a bolt. There will still be a gasket though. Turn fuel off before trying to service.

If fuel is running out from inside the carburetor (through air cleaner, etc), then you have a float / needle that is stuck. This is quite common after a small engine has been in storage and fuel was left in the carburetor. The residue causes the float to stick to the bottom. Turn the fuel off, undo the bolt that holds the bowl on, and carefully remove the carburetor bowl. Use a can of carburetor and choke cleaner to spray out the "gunk" in the bowl, spray off the float, and then reassemble. If it still leaks, then your needle seat will need to be replaced as well.

Well it seems to flud n only starts ever cupple days


Adjust/clean the float bowl in the carb. Carefull not to bend the float tab when cleaning. Draining the float bowl wont solve the problem, but it might get you started up. If it is not in use for long period of times, add fuel stablizer, turn of the fuel valve, and run the bike untill it stalls out.

Fuel leaking back to oil


hi,might be able to help,if this is a carburettor model,then you may find that you have a stuck float in one of the carbs,this will allow fuel to continuosly run throgh the carb even when the bike is mot running,the fuel will then run through the inlet manifold into the engine cylinder,past the piston rings and into the sump,the other problem could be the float needle valve has come loose in its holder causing the same problem,check your fuel tap(if fitted) and make sure it is not in the "pri"position,this will also allow fuel to run unchecked into the carbs and ultimately overfill them,causing the same symptoms as above,either problem except for the fuel tap means you are going to have to pull the carbs out, remove the float bowls and inspect the float needle assembly...hope this helps...cheers ian

Mowers is not getting gas


Check your float ... it might be sticking in the upward position when the fuel well fully fills? This would cause the mower to run on the fuel that gets inside the line when you prime it, but since the float stuck in the upward position would close the intake line from the gas tank, your mower would die after the priming fuel is spent.
[The float is located inside the metal bowl beneath the carburator usually, and can be opened by removing a single bolt/screw in the center of the bottom of the bowl. Be careful to pay attention to how the valve-pin attached to the float is attached; usually it's just hooked on very loosely. Thouroughly clean the float, pin & inside of the bowl, then reassemble after making sure the float moves freely.] If the problem isn't solved by this, you might have an obstruction (like a leaf-cutter wasp nest) in your fuel line between the gas tank & carburator? Check the float first.
