Glad to hear it was easy :-)
Here is a link to my trouble shoot solution so that this will get marked as solved.

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,

Rate me if you liked the answer,

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

there is screws that mount it to the main frame take those off then the engine is free but still with the electric parts ther are screws that take apart the engine from the generator unscrew those with a socet rench than insid there will be 4 more take them off and the it is one engine with no generator!!!
the only problem is now your gas tank is in the top off the frame so you will need a different gas tank it you will build somthing around the engine itself.
That one was easy!
use your eyes!!!!!

There are two kinds of control switches in the electric start system of generator set: electromagnetic type and mechanical type. The electromagnetic switch is driven by the electromagnetic force to pull the fork to start. When starting the diesel engine, press the switch. At this time, the circuit is as follows: the battery switch, the connecting post 5, the iron absorption coil, the connecting post, the generator and the iron battery. The current flowing through the iron suction coil makes the core magnetized to produce suction force, and the moving contact is sucked down and closed with the static contact.

It probably isn't the circuit breaker. The magnetic field has likely weakened (especially if the generator has not been used in a while). The magnet can be "flashed" by running a current through the generator briefly. The easiest way to do this is to plug in a motor and spin it backwards (by hand) while the generator is running (e.g. an electric drill). The drill acts as a weak generator when you put the energy into it by spinning it.

A previous answer I gave to the same problem...
Look in the manual. There is likely something about field flashing the magnetic field2.gif. According to the Briggs and Straton web site (similar solution for all generators), the easiest way to do this is to.
1) start the generator
2) plug an electric drill into the generator (without drill bit)
3) make sure drill is set to forward direction (if a reversable drill.
4) pull the trigger on the drill.
5) If the drill does not start, spin the drill's chuck in reverse [clockwise (When looking down at the chuck from the drill bit end). Spin counter-clockwise if holding it like a pistol and pointing away from yourself].
6) Do this several times (hard) until the the generator will kick in and suddenly make the drill spin at full speed.
Be careful not to drop the drill or poke someone with it as you celebrate success.

The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.

How do I find a replacement carburetor for my pm0645250?

Coleman... | Answered on Oct 06, 2016

that will work fine in that engine.

The easiest way to do an ignition check is to MAKE SURE the right amount of oil is in the engine, make sure there's FRESH fuel in the tank, and then where the on/off (I/O) switch is for the engine, not for the generator half but for the engine itself, there should be atleast one if not a cluster of wires with disconnectable links on them. Disconnect them, those are all of your ignition wires from various areas of the engine and generator that will kill the ignition if something isn't right. If you disconnect the main one from the on off switch, there should now be a spark but be careful because with all of that disconnected, you won't be able to shut the machine down easily, you'll have to remember which wire goes where that you disconnected (good idea to photograph them before you disconnect more than one wire) and either reconnect them, choke out the engine which may not kill it either, or disconnect the coil to spark plug lead from the spark plug. An easy way to check for spark without disassembling anything first, is to get a long Philips screw driver with a plastic or wood handle, and stick it in the coil lead where it would go on the spark plug. Hold the handle and bring the shaft about 1/8" or less without touching it to the tip of the spark plug that's metal and exposed. Have someone pull over the recoil once and check for an arc going from the screwdriver shaft to the plug. Make sure the I/O switch is on and being in a dimly lit area helps to see the spark as well. Don't worry about getting zapped, it won't kill you an it doesn't hurt, just feels like a violent vibration isolated to the area you are touching and instinctively your body will release from it and you should pull your hand back. But, if you follow my instructions and use the correct handle material screwdriver and don't touch any metal, you won't be shocked, promise. Chances are, you DO have a spark and there is nothing wrong with either the coil or the plug as it rarely ever is in no-start situations. More than likely your fuel has gone bad and is not making it to the engine. You can even avoid all else I said, and simply pick up a can of carburetor cleaner NEVER STARTING FLUID, and once you have the air filter completely removed and can see the throttle plate, hold it open, spray a quick shot of the carb cleaner into the engine, and give it a yank. I almost guarantee it will try to fire on the carb cleaner and once it runs out, will die again. That means you aren't getting fuel and need a new carb. Yes, a new carb, because taking it to a place to have them remove it, rebuild it, and reinstall it while trying to sell you other services will be infinitely more expensive than a simple $50 carburetor.

check the operation of the on/off switch
