Hi Mark,

The engines used on the Powermates have a low oil shutdown system that can be troublesome. Try this:

1 - Make sure there is enough oil in the crankcase. The oli level needs to be all the way up to the bottom of the threads in the oil fill hole.

2 - Still no spark? Replace the spark plug with a new one (properly gapped), then spray something like brake cleaner into the carb. Pull the rope and see if you hear any detonations from the engine. If the engine tries to start but won't you need to look at the fuel system, then the ignition.

3 - If you proved there isn't any spark happening, look under the plastic cover where the kill switch is located. You'll find a small metal box with wires coming out of it. Find the wire that goes from the box to the kill switch and disconnect it at the switch. Mark things as needed so that you'll remember where to put them back. Give the rope a gentle pull and see if we have a working ignition, if it does have spark there is something wrong in the low oil shutdown mechanism.

4 - If you've convinced yourself that the low oil shutdown is misbehaving try changing this oil and flushing out the crankcase. Look for any evidence of debris that would have made the oil level float bind. As a final test reconnect the wire we took off the switch and disconnect the one that goes from the module to the oil sensor on the side of the engine, if you don't get a spark with the sonsor disconnected you probably have a bad module.

5 - If we didn't get ignition with the low oil shutdown disconnected from the kill switch, reconnect the wire we took off and then disconnect the (usually black) wire that leads down inside the engine. This is the kill wire for the ignition module. If you get the engine to start with this wore disconnected you may have a shorted kill switch, test it with an ohm meter.

6 - if there still isn't a spark with the kill wire disconnected you may have a bad ignition module. You have to take off the carb, then the blower housing to get to it. Check that the kill wire isn't shorted to the block anywhere, and that the module has the proper gap and orientation before replacing it, The modules say "cyl side" on the side that should face into the engine. A regular business card or a playing card ought to just fit between the magnet on the flywheel and the module, too loose would cause a loss of ignition. You get extra points if you use a feeler guage to set the gap to 0.010 inches.

7 - Ignition modules are available from a bunch of different places, your local Briggs supplier will want to know the model, type, and code numbers located on the side of the valve cover in order to be sure which parts you need,

This will depend on the use situation of the generator. If its proformance is still good, resale value is higher. Contrary, its resale value is low.

Low oil doesn't usually make engines cut out. Clean the air filter, change the plug and wire. If this doesn't help then I think you're looking at a carb. problem. Probably just clogged jets & ports. It's very common on small engine carbs. It shouldn't take more than 2 quarts of oil. Probably not even one.

Try to locate a plug in voltmeter that also measures frequency. set engine speed for 60 hz with moderate load.

What does the oil look and smell like? Also what conditions is it been ran in lately, and what fuel are you running?

Coleman... | Answered on Mar 11, 2019

Most Generators utilize a GFI receptacle (s) along with push button resets. With nothing connected push the reset button on the GFI's and then the small reset buttons. You should see a small green light on the GFI's letting you know they are energized.
