My troy-Bilt 5550 watt generator will not start

The generator was stored for more than a year with fuel stabilizer and full oil. Fuel was changed but generator will not start. Tries to start with starting fluid added to carburator but will not start completely. Spark plug also has good spark.

First drain the fuel bowl. Any old fuel in there will keep it from starting. Fuel stabilizer is not what it's it cracked up to be. I've worked for 6yrs at a rental yard and had no luck with any fuel stabilizer, the fuel still went bad. If after you drain the fuel bowl it still will not start, you will need to clean the carb. Remove the carb and spray carb cleaner through all the accessible passages. If this does not do it, you will need to replace the carb. For long term storage I highly recommend draining all the fuel and filling just the carb with fuel stabilizer to keep gaskets moist. Then drain the carb when you take it out of storage.

Just solved same problem on Troy-Bilt 5550 generator (Briggs and Straton 10 HP OHV motor): Invert generator. Remove shield covering carb bowl. Remove carb bowl (2 screws). Remove carb bowl and spring (spring holds float in position) from carb body. Remove plastic float assembly from carb. At bottom of float assembly is metal orifice which is fuel pickup. That is plugged. Clean it out with (for example) carb spray cleaner. Reassemble and test. Worked like a champ for me.

I have a Troy-Built generator as well. Carb repair kits are available on the B&S web-site. Booklet number is 204400 for all of the parts. The carb orifices are very, very small and clog easily with the smallest of particles. These generators are very ticklish to tune up. Best to change the springs if they appear corroded at all and remember which peg hole the governor spring was removed from... there are about 20 different holes which vary the spring tension. To do this, you need to remove the on/off switch cowling. These engines do not do well with regular or ethanol doctored gasoline. Ethanol added gasoline will ruin the seals. They generally are not intended for continuous, heavy duty use. If you want a heavy-duty generator, that is allowed in National Parks (meets noise criteria), buy an Onan and forget about it.

Where is the carberator on the troy-bilt xp series 7000 watt generato

    You need to remove the air cleaner and the housing that supports it. There will be two Inverse Torx screws that you can remove carefully with Vise Grips to remove the carburetor. You should have something ready to plug the gas line... a whitled stick is fine so you can detach it. A pair of regular pliers is great for grasping the hose clamp and sliding it upwards.

Will not start generator starts but will not continue to run (as if not getting fuel)


Problems with generators is that they are only used in emergencies. The fuel in the tank gets very old and the fuel in the carburetor breaks down and clogs the passages.
The fuel should be changed once or twice a year and the carburetor needs to be taken apart and cleaned. Any automotive supply store should have carb cleaner.
Add fuel stabilizer to your fuel tank and run the generator for a while before storing it. It also doesn't hurt to run it for a few minutes every month. At least you know it will start when you need it.

What is the problem of my generator to stop automatically


First thing to check is the oil, could be a low oil shut off which is a very good thing to have!

Any equipment the sits a long time, check the oil first. if hi, see if there is water in the bottom (rain thru exhaust), if hi but thin, gas leaked thru carb, piston rings, and into oil. do not run until drained and new oil.

Most common problem would be old fuel and or water in the fuel. any small engine with occasional use should be kept near full with hi octane fuel with fuel stabilizer in it. any gas I by in the can gets stabilizer in it, as modern fuel gets more like kerosine after a month or so, and who knows how long it will be before it or equipment burns it all up. Keeping it full also reduces condensation of water vapor in the tank.

If you can drain your fuel from the carb., do it. If not easy, then add a bottle (or less) of fuel line anti-freeze then add good hi octane fuel. A drop of water in the carb. will keep it from running, especially when cold, (when hot it will vaporize and then restart). occasionally a spray of starting fluid will help get started and suck good fuel into system.

1500 not start


Did you leave any gas in it as it was being stored. If so then your probably looking at dirt or varnish in the carb. It this is the case you will need to taske the carb apart and spray the inside with some carb cleaner then make sure to wipe it all out. Next time you store your generator make sure that you compleatly drain all of the fuel. If not then be sure to add some gas stabilizer.

Good luck,

3650 generator won't start!!


I assume that the spark plug are good and the gas line is clear. Try to adjust the gas line supply and default engine startup revolution settings try it full half and minimum back and forth it works. Other gen sets requires a mix of oil with its gas, please do it when it is required with exact proportion. Hope this helps. Goodluck.

Unit stored 4 months, full fuel - stabilizer added, battery tender attached. Now unit starts runs briefly then quits, will not restart, wait for awhile and it will start but same issue occurs, checked fuel...


right before you stored when you added the fuel stabilizer did you have fresh gas and did you run the engine with the fuel stabilizer in for 5 to 10 minutes

I have an old makita g2700 generator with a robin ey25 engine.i need to change the oil.what grade of oil is recommended please


Hi Tim,
That engine's original production started out in 1987 by Teledyne and then taken over by Robin Subaru. Replacing your oil depends upon your climate, here's a list Below 14 degrees F 10w30 14-68 degrees F SAE #20 68-104 degrees F SAE #30A complete fill requires 28.7 OZ of oil according to the service manual.If the engine is burning a lot of, oil I would suggest that you jump up a rating on the oil. For example if you are in Florida and it's 95 degrees outside I would useSAE #40. If the engine is still within its tolerance and not consuming oil I would stick with the factory recommendations. On a further note,This is a fairly old generator and was designed to run on straight gas, NO ETHANOL!!!! Today's gas has at least 10% and it will wreak havoc on your fuel system. Ethanol will absorb water from the moisture in the air, It bonds with the water and sinks to the bottom of the tank. Gas with ethanol has a shelf life of about 30 days. Ethanol will also act as a solvent on the fuel line, creating a gum on the inside of the line and make the line very brittle. The gum will eventually migrate into the carburetor and foul it. I would strongly suggest that you replace the fuel line with Tygon or any other ethanol safe material, I would also swap out the fuel filter or add an inline one. Do not store the generator full of fuel, store it empty. Check out the website pure-gas.org to see if ethanol free gas is available in your area. It will last much longer especially with a little bit of Stabil in it. Good Luck,Michael Burke

Have a 2005 homelite generator that I can not start. Have oil that was in before. Added gas. Flipped switch and hit the choke. Pulled chord and nothing.


Check the following:

1. The fuel - if old fuel was left in, it may be contaminated. Use fresh fuel. If the unit isn't used regularly, add the gas additive "Stabil" before storing the generator.

2. Check the air filter - clean or replace as necessary

3. Check the spark plug for fouling, gap, etc.

4. Make sure the carburetor is tight to the manifold and engine.

5. Make sure to start the unit with no loads connected.

6. Makes ure there is enough oil and the correct type in the engine - do not overfill.

Generator stored in garage, we run it once a year to make sure all is well. Hurricaine coming, got out generator put in new gasoline, set in choke position. Generator tries to start, but will not stay...


If there was old fuel in there before, you will need to clean the carb the jets are clogged. Or worst case you could have water in the fuel tank but try to clean carb first. Good Luck...

Used to start, but doesn't after sitting for several years. A friend suggested to try adding new fuel, checking/cleaning spark plug and checking oil for a gray hue (which means water present). If gray then...


Hello, yes fuel does go bad. So, I would drain the tank entirely, the carb, change out the fuel filter (if present) and add new fuel. Now, you can take some WD40 and first remove the spark plug then spray some WD 40 into the cylinder (through the spark plug hole). Screw the plug back in and then connect it back up, pull the starting rope and see if the engine fires. It should fire up. This tells us that the ignition system is good. Now you can use this technique to start the engine with the fuel turned on. What you should purchase is some in tank carb and fuel cleaner before you fill the tank and turn on the fuel. There may be some gasoline varnish deposits in the carb that need to be cleaned out. Try all the above, and see if it starts up. If keeping the unit stored for a long time, you can purchase and install some fuel stabilizer for the gasoline.

Wont start has spark , new fuel, new oil.


Is the spark plug black?
It won't run well with a carbonized plug.

Is the main jet in the carb plugged?
If the plug is dry after trying to start it.....your fuel is not getting into the engine and most likely a plugged carb jet..
Also.....Is the fuel switch working...is it in run position?

If the generator has sat for a while with fuel left in the carb/fuel tank.......the most common problem is a plugged varnished dirty carburetor in need of a good cleaning.
Always shut the fuel off and let the carb run dry (run until the engine stops)before storing.
Add fuel stabilizer to any remaining fuel or drain the tank before storing.
