A coleman generator 6875 won't start please give

Check for spark. If no spark, check ON/OFF switch and oil pressure sense failure).

If you have spark, then...

Low fuel
Or
Water in fuel tank (fuel system)
Or
Stuck carburetor float
Or
Crud (and/or water) in carburetor bowl

Drain all fuel from tank. Remove and clean out carburetor bowl. Reassemble.

Use fresh gasoline and try again.

You will need to contact a Coleman dealer to purchase any parts. Fixya.com has no resources to order or sell parts for any consumer product.

Field Flashing of Portable Generators This tip comes from the Briggs & Stratton Customer Education Department. As an alternative to flashing a rotor winding with a battery applied to the brushes, an electric drill may be used. Follow these steps to flash the generator:

• Plug the electric drill into the generator receptacle. (Cordless drills do not work)
• If the drill is reversible, move the direction switch to the forward position.
• Start the generator
• While depressing the trigger on the drill, spin the drill chuck in reverse direction. This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the reverse switch positioned backwards.

Use caution not to get your hand or other materials caught in the chuck. As soon as the field is excited, the generator will produce power and the drill will turn on.
The reason this works is because the electric motor in the drill will act as a small generator when spun backwards. The magnets in the drill's motor induce a voltage into the motor windings, which is fed back through the trigger, cord and into the generators receptacle. From there it goes into the power winding of the stator. The voltage going through the power winding creates a magnetic field, which is intensified due to the iron core of the stator laminations. The rotor intersects this magnetic field as it is spun past the power winding, thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed.
If flashing the field does not make the generator work, you may have additional problems, besides a lack of magnetism in the rotor. Further testing will be needed. Hopefully, this will give a simple way to field flash your generator if needed - Bruce Perrault

check this web site http://www.powermate.com/productmanuals.php?cat_id=3 you can down load the manual and parts list for your gen.

I'm not familiar with this particular generator but starting most of these is pretty much the same.

Turn all switches to the generator OFF locate the Carbuerator and put the choke on if it has a small bulb pump it a few times, now here is a trick I use I buy a can of starter fluid and spray a quick spray close to the air intake or air filter. This should work.

Hi,
If you've got an auto idle function you'll also have a switch somewhere to shut it off, so look for that first.
Engine surging is almost always a problem somewhere in either the air cleaner or the carb. Check the air cleaner, if it's not dirty take the bowl off the carb and look for dirt in the bottom.

Check the oil level, these generators have an oil monitoring system that prevents the engine running if the oil isn't all the way up to the bottom of the threads in the oil fill hole.

I posted an answer that should help, click here.

Hello, If your generator has sat for a long time, the residual magnetism in the field coil may have dissipated completely this will cause the generator to produce no electricity. If this is the case there is a fix that is so simple it will amaze you by how easy it is to get it running properly again. The process is called flashing the field and it is done with an electric corded drill. Here is a link on how to do it. http://www.perr.com/tip16.html I hope this helps. If my solution works for you would you kindly give me a positive rating. Thank you, Michael Burke
