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...

SOURCE: Coleman6250 Generator PM0545007 - Won't start/run.

Most gasoline engines need three basic things to run: proper air/fuel mixture, sufficient compression, and a properly timed spark. Check the easiest, cheapest things first, then check the "Gee, I forgot to turn on the gas" kind of things next, then work your way onwards from there.

Compression can be guesstimated with the proverbial thumb-over-the-empty-spark-plug-hole routine as you turn it over casually to check compression. If it doesn't blow your thumb out of position, you could have a hole in the piston (overheating response) or a stuck or damaged intake or exhaust valve.

Check for fuel flow by carefully disconnecting the fuel line to the carburetor and letting some run into a tin can (no styrofoam coffee cups, please). It should dribble freely. If not, you have to back-track the line and find out where the blockage is.

Spark is one that sounds like you've already tested (spark plug out of the cylinder head, hooked up and laying on the metal engine as you turn it over?) so check timing. You will probably need a manual for this test, although a good estimate is that the plug should fire just a wee bit before Top Dead Center position of the piston. Like I said, a manual comes in handy here.

From what you've mentioned, though, I'd start trouble-shooting at the fuel flow part first.

Good luck,

GRB

How long does it run? The 'oil pressure' switch will cause that....??

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!

On this cart, I have cleaned out carb twice. Battery good. It runs shortly then dies out. Micro switchesx4 has been replaced. Spark plug good. Gas is good and getting to carb.


Determine if it is running out of fuel or no spark.
If it stalls but will run on carb spray or starting fluid
sprayed in carb opening then the fuel has problems.
If it will not run on the starting fluid then the spark is weak
or failing due to bad wiring or coils. Once you isolate
the problem to fuel or spark then you can probe those areas.
Be sure compression is good also. 100 psi at least.

Scag zero turn 52"deck tiger mower


If you have spark, compression, and fuel to the carb but not at the plug. You have a clogged carb. Try starting with starting fluid, if it fires briefly, your carb needs to be removed and cleaned.

check crank position sensor or immobiliser system as you have not spark at the right time. Immobiliser may be a battery problem in the key unit. Have the codes read

Cub Cadet has gas, has spark, has air -still won't start/run


Are you pulling the plug to check for wetness after cranking it a few times, WITHOUT using the starting fluid? Also, I would recommend using carb cleaner in place of the starting fluid. Starting fluid runs the engine VERY hot for a brief time and can possibly damage rings, valves, and aluminum parts.

Sounds like the carburetor is plugged up on this generator since starting fluid starts the engine.

Briggs and Stratton 6.5 hp won't start- not sure gas is getting to the spark plug, just overhauled the carb, changed oil and new spark plug


First you could make sure you have spark. Take the plug out and then plug it into the black wire. Set the end of the spark plug near the frame of the lawn mower. Pull the cord one time to see if there is an arc from the plug to the mower. If you have spark, I would put the plug back in. Before putting the plug back in I would spray a little bit of starting fluid. See if it will fire up with the starting fluid in there. If you have a true good spark, it should fire up. This may be enough to get some gas going in there as long as you have the lines hooked up correctly.

Model 180 John Deere garden tractor won't start


*cyliniod sticking... try banging on it with the blunt end of a good heavy screw driver / or the handle of a hammer. might free up the contacts, or it might be too rusted inside...

*yes to the first part about starting fluid...the starting fluid should have fired off the motor for a few seconds...so since you didnt get anything after this, it sounds like your not getting adequite fire to the cylinder (s) .
i would try a new spark plug since that would be the cheapest thing to start with first.
