Question about Coleman Powermate Subaru 5000W Portable Generator

1 Answer

My Powermate 5000 generator with subaru engine worked great for the first two or three years. It started shutting down after a few minutes run time, so I suspected low oil. I filled the oil and then did not have a need to use it for a year or so. Now it won't start. I am getting spark, so I checked the carburator. I cleaned the venturi and blew everything out carefully and reassembled. Still no change. If the low oil switch was bas, I assume I would not be getting any spark. Any other ideas? Many thanks!

You are correct about your assumption of oil sending unit, however, I would still disconnect the wire from sensor for now. I assume that you drained all the old fuel from the tank and bowl. Add one gallon of premium grade fuel into tank. Remove spark plug and spray carb cleaner into cylinder or remove air filter and spray carb cleaner directly into carb while cranking. Don't over spray, just enough to get things going. I suspect that the valves are not seating. This may improve after it cranks up. Use some upper engine lube in fuel after it runs. If it does not crank please check compression and email the results. Good luck and thanks,

The generator hasn't, been used in a while and is not cranking. Gas is getting to the spark plug and the plug is clean. What could be the issue?

I HAVE A POWERMATE 5000 THAT SHUTS DOWN UNDER LARGE LOAD . I THINK I NEED AN IDLE CONTROL MODULE.THERE IS A 2 WIRE MODULE IN THE START CKT. #21009XA IS THIS IT AND WHERE DO I GET ONE .


Idle control comes into play when there is no power draw forcing the engine to idle with an electro magent. If you feel that the electro magnet is interfering with governor, temp remove the wire to the solenoid. Usually the idle control will not effect how the engine /gen output power. An overloaded condition will cause the engine the go the full throttle as the internal governor of the engine will try to maintain 3600 rpm. Overloaded condition will greatly shorten the life of the generator/engine. Try to use only about 80 % of rated power. Large motors can draw three times running amps. A compressor using 12 to 18 amps to run can draw over 40 amps to start.
If your generator could handle the load in the past, check the engine for loss of power, or the generator for faulty voltage regulator or capacitors out of range. Easy to check. Connect digital volt meter to plug /load and look at volt reading while running with no load and loaded. Voltage should stay between 110 to 120 under load and with no load (unless goes into idle mode). Good luck

My powermate 5000 with subaru engine will run anywhere from 30-60 minutes and shut down. One light pull to the pull start and it runs great for another 30-60 minutes. Never a problem to start it back up...


There is debri or dirt in gas tank and eventually it gets sucked up and clogs the screen filter on the end of gas line. Drain gas tank and flush out a few times. let dry and put new gas in it. check your gas can, if it is metal, it may have rust in the bottom of it and it goes in the gas tank and clogs screen, make sure you have a clean gas can that you use to fill the generator.

What brand of engine & horsepower is it?Also about how long was it stored or last time it was run? The reason I ask is if it was stored with gas in it & a fuel stabilizer wasn't added to it,your primary jet is plugged in the carburetor(reason it will only run while choked).

Check the vent in the fuel cap to make sure its free to breath. It could be creating a vaccume in there and starveing for fuel. Maybe run it with the gas cap off and see if the problem gos away.

Try removing the float bowl from the carbuerator and empty it out. Also check the float valve to see if there is debris under it. Thi problem is definitely fuel.
