Question about Electrical Supplies

Open Question

My Coleman PowerMate 1850 is not getting fuel into the carburetor. What do I need to do to solve this problem? I cleaned the float pin, float and bowl when gas poured out from the carburetor. I assume this issue was do to fuel being left in the generator a long time without use. The generator gets spark because it runs for 10 seconds or so after I spray starter fluid in the throat of the carburetor.

SOURCE: coleman powermate 6250 generator will not start

I have one of these generators, and I can tell you that at least once a year, I have to pull the petcock type assembly off tank, and clean it. I also drain and clean the tank. It gets a sediment build up, and the petcock system isn't the greatest in the world. I'm going to say that you either have a problem in the petcock type assembly, or you have a stuck jet in the carb, either of these can happen with it sitting for the long period of time. Start by removing the fuel line to the carb and checking the fuel flow. Sounds like you may have already done this, I'm unclear on that. Then I would remove the carb, and soak it overnight in a penetrating oil. This will loosen up any rust or parts that may be sticking. One other thing you may consider, depending on where you live, you may have a mud dauber or wasp nest in the intake or other critical area of the engine. I still get amazed at where I find mud dauber nests occasionally, the little buggers seem to be able to get anywhere.

SOURCE: Coleman Powermate 5000 starts with starter fluid, but leaks

Sounds like you need to clean the carb ports, lines, jets, etc... purchase a carb spray cleaner with a tube to place on the spray head (Berryman's Chemtool B-12 is awesome). Take the carb loose from the generator, and remove the bowl, needle valve and spray carb cleaner thru all the holes, lines in the carb. Reinstall complete with air cleaner and retry... also if the gas is old, drain and replace with new...

Bascially you need to completely remove the old, stale fuel to start with. (you can use the old fuel it in your lawnmower mixed 50:50 with fresh fuel to use it up).

Then once you've drained the fuel tank, you'll have to clean out the carb with a Fuel Injector and Carb cleaner. Really spray the carb till it's soaked, since you've got a schellaced fuel system.

Make sure you remove the air cleaner so you can get the spray into the carb. Also, with the spark plug removed, and the power switch turned "off", so the generator won't try to start during this process. You can also slowly crank the engine with the pull starter, to help work the cleaner through the system.

Then let the unit set for about 10-15 minutes, so the cleaner can evaporate, etc. and then you can reinstall the spark plug.

Now add about 1/2 gallon of fresh fuel and you can try starting the generator. You might have to use some starting fluid to get it started, by carefully spraying it into the carb in very small bursts to keep the motor running

Once it's running smooth, you should always use fresh gas and make sure to add a quality fuel stabilizer, such as Sta-bil, to the gas you use in the generator, as it will keep the fuel system protected for up to 2 years.

I also always turn off the fuel shut-off on my generator to use up the gas in the line before storing it. Also, you should get the generator out at least every 3 months and run it for 15-20 minutes to keep everything working and lubricated, so it will work when you need it.

Just be sure to always add more Sta-bil to your fuel and turn off the fuel shut off and let it run out, before storing.

I've done this with my generators and they're now over 14 years old and always start on the first pull and run like tops!

If you can't get the unit running smoothly, you may have to take it to a small engine service shop for them to do a "tune-up" for you.

Hope you find this Very Helpful and best regards!

SOURCE: want to remove the starter recoil from my powermate generator

I got one of these pieces of junk, and had same problem you described.

You will need to remove the end panel to get to the blower housing. You will have to thread the rope through the handle until you have enough slack to remove the rope from the handle. The end panel should now be free to remove entirely.

Find the 3 bolts that hold the blower housing on, and remove them. Once you get it off, make sure that the rope has a knot in it so it won't get retracted into the pulley recoil assembly. Take a screwdriver and push the rope back down into the pulley (that was my problem). Assembly is opposite of taking apart.

I have a Coleman PowerMate 1850 and it fails to run more than a few seconds. The fuel, gas and switch are on but it sounds like it is not getting gas. I run the carb dry after each run and use a fuel...


sometimes if you "run dry" you can shrink the needle valve on the float bowl. when you fill with fuel it will get stuck in the hole that lets the fuel into the bowl.

Gas leak out or the carburetor


Thiis usually caused by a failure of either the float valve or the float itself.

Bad float needle valve: If some dirt or other particle gets stuck on the needle valve or seat, the valve will not be able to completely close and fuel will continue to flow into the bowl and eventually overflow. A new needle valve and seat are < $5.00 on-line.

Bad float: If the circular float gets a hole in it, fuel will get inside and the "float" will get heavy and no longer float on top of the fuel in the bowl. Because it doesn't float it will not rise high enough to push the needle up into the seat and keep extra fuel from entering the bowl. A new circular float is < $10 on-line.

Float in carb.


Hi Stan,It sounds like you are missing your float needle. There is no reasonable explanation for it to disappear if the float was not removed.The float needle is typically made from aluminum with a black conical gasket tip to create the seal when the float is in the raised position to stop the flow of fuel. They are fairly inexpensive to replace. Seeing that your generator is a Powermate 5000, if it is an older unit using a Tecumseh engine you will have to be very specific with serial and model numbers, since Tecumseh has gone out of business. Replacing the float needle is fairly easy. Some carburetor bowls are formed with an uneven bottom to allow proper travel of the float and they must be re-installed in the correct orientation. If the bowl is round and completely flat on the bottom the orientation doesn't matter. After the bowl is removed the float needs to be removed also. Where the float hangs on its hinge there is a stainless steel pin that needs to be removed, some carburetors have a nub on one side that allows the pin to be removed in only one direction. A finishing nail that is smaller than the pin will push it out with little effort. On the top of the float as it would be oriented in its installed position there will be a horse shoe shaped receiver that the float needle slides into, there also might be a small spring in the replacement, be careful with this spring it is easily damaged and easily lost. The float needle is placed into the receiver on the float, then carefully take the assembly and slide the float needle into the orifice while the float is lined up to go back into its hinge. Align the float to receive the hinge pin and slide it in. Make sure that your bowl gasket is in good condition and replace the bowl keeping in mind if the bowl is formed for float swing travel. Add a little gas and check for leaks. If leaks are present the causes will be bad gaskets either on the top of the bowl or the bottom by the nut. Another cause could be that the bowl is rubbing on the float and keeping the valve open, loosen the nut and rotate the bowl until the float swings freely then re-tighten and check for leaks. Last but not least you have the wrong float needle and it is not long enough to seal correctly when the float has risen to the full position. Good Luck,Michael Burke

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.

I have a coleman 6250 generator, only runs when i spray fuel into the carb, it about a year old. With a B&amp;S engine


Old gas has probably gummed up the works. You have to store these with an empty tank to avoid this in the future. Using a fuel stabilizer helps too. To fix it, remove all of the old gas. Make sure the fuel cutoff valve is open (it only turns 1/4 turn). If it has a fuel filter replace it. Put in just a little fresh gas in the tank with a bit of carb cleaner. If it still won't run, remove the carburetor bowl and you will see a donut shaped float that operates a valve. Using carb cleaner, clean that valve, and clean the needle valve in the middle of the bowl. Good luck.

I have a 5000 watt pm0525312.17 generator and it is leaking gas any tips


Hi and welcome to FixYa. I am Kelly.

Lets start with the obvious.
1. Check all the fuel lines for cracks at the fittings

If it is leaking from the Carb Float Bowl then there is probably some debris in the needle and seat area.

FUEL SELECTOR "OFF"
- Remove the mounting screws from the float bowl mating area and the bottom nut.
- Using something like a spray can lid hold it under the carb and turn "ON" the FUEL SELECTOR
- Gently raise and lower the FLOAT assy checking to see that fuel flows when lowered and stops when raised level.
- FUEL SELECTOR "OFF"
If it does not stop you will have to remove the Float pivot pin by removing the phillips screw locking the pivot pin in place. Then the Float and needle will drop out down off of the Carb.
- Check the POINTED needle assy rubber area for any signs of unusual wear. If it has any notches in it or is not a smoothe taper to the tip then the needle will have to be replaced. If the needle is damaged, the seat up inside the Carb will also have to be replaced.
- Re-install the needle and float assy making sure to lock the pivot pin with the phillips screw.
NOTE: IF you can to this without removing the whole carb assy it will save you lots of headaces getting linkages correct later.
- FUEL SELECTOR "ON"
- Check float for proper operation
- FUEL SELECTOR "OFF"
- Reinstall the Float bowl NUT (Loose) making sure the gasket is in the proper alignment.
- Install the mounting screws Tighten the Bowl nut
- FUEL SELECTORr "ON"
- Check for leaks of gasket, nut and in general.

This should solve your leak problem.

Thanks for using FixYa.

Colman Powermate Generator will not stay running


This overflow can be caused by:

1. The float sticking

2. Gas inside of the float air chambers

3. The needle and seat have debris in them or a r damaged.

It is not a difficult fix but it does mandate removal of the carburetor float bowl.

You could probably do this yourself. It is much easier if you place the generator on a high work area so you can see the float and needle once you have the float bowl removed. Just make sure you do not drop the float assy so far that the needle comes out of the seat unless you have to remove the hinge pin SCREW for the float to clear the debris near the needles' pointed rubber head.

How do you start it cold


I always turn off the fuel and run my carburetor dry so the fuel will not go bad. If the generator has set up for anytime I will do a fast carburetor cleaning by removeing the float bowl and clean with carburetor cleaner as well as any line, port or oriffice then reassemble and start with new and clean fuel.

Coleman 6250 generator runs rough


Fresh fuel? Does carburetor have adjustable jets? Turn the high speed jet (at bottom of float bowl) about 1/4 to1/2 CCW (looking at bottom of bowl). If no improvement, carburetor should be torn apart and cleaned. This also applies if there are no adjustable jets. Is there a fuel filter anywhere?
