Brand new troy bilt 2410. Just put in new Clean fuel and oil. First time used this winter. won't start and snow coming.

SOURCE: How do I clean the fuel line on troy bilt 5hp chipper vac?

unscrew the nut on the bottom of the carburetor and remove the float bowl it must be emptied and cleaned , debree and water gets into the bowl and blocks of fuel flow reinstall the bowl and start, some carbs don't have a float bowl requiring you to remove the gas tank and carb which is a more involved cleaning.

Hello,

You need to remove the carburetor float bowl and clean it. The needle and seat also need to be cleaned. The best thing is to totaly remove the carb. and soak it in a commercial/professional strength cleaner.

Your problem is fuel related, but just to make sure, remove the spark plug and spray some carburetor cleaner in the hole, replace the plug and give it a pull. If it fires up then quits..... The fuel system is to blame.

Hope this helps, Matt

Hello,
My name is Dane and I am going to assist you in solving your problem.

The first thing I would check is to check your spark plug and then make sure your gas cap is venting properly. If the vent gets clogged, the tank will actually get a vacuum built up and no gas will flow to the Carburetor. The next time the mower does this, loosen the gas cap enough to allow air to get in and then retighten. If it runs fine, it was clogged. You have to clean out the vent or get another cap.

Make sure the fuel is mixed correctly. Too much oil in the mix will cause problems. Make sure you haven't left old fuel in it for a long period of time and gummed those jets up. Sometimes an engine just needs to run in order to clean the jets out. If this is the case, just replace the fuel, get it running and work it normal for a tank of fuel if you can. You should see improvement by then.

If it still doesn't run correctly, you will have to adjust or clean the Carburetor. One thing to remember: If your engine has run fine in the past, you probably have a clogged Carburetor. If it hasn't ever ran right, you should adjust the high-speed jet.

If you need to clean the Carburetor, you will probably need to remove, disassemble, soak, and use compressed air to blow out the jets in your carburetor. Pay close attention to how the carburetor is attached to the engine. Make a drawing if you need to or take some pictures. Remove the Carburetor from the engine. Remove the air filter, linkages, throttle/choke cables and fuel line. Remove the mounting bolts/nuts. You will need to disassemble the carburetor as far as possible and put it in some Carburetor cleaning solution. You can get this at any auto parts store. Do not place rubber parts in the solution. Allow it to soak in cleaner as directed, and then blow out the ports and jets with compressed air immediately after you take it out of the cleaning solution. Be careful not to get any spray back on your skin or in your eyes. Reinstall the Carburetor in the reverse order. Replace any worn or torn gaskets or o-rings as you assemble and reinstall it.

If you need to adjust the high-speed mixture setting on your Carburetor, turning the screw out just 1/2 turn or so should do the trick. It is not so hard to adjust the Carburetor, however you do need a special tool that is very hard to get your hands on. They don't make many engines with plain screw heads on the jet screws anymore. The newer Carburetors are factory set lean so they can pass emission standards. If you have a local dealer, they should adjust the mixture for a couple of bucks. If you can adjust the screw, start the engine, allow it to warm up, and apply full throttle. Start backing off the screw just until the engine gets max RPM. That's it. You're done.

Just a TIP: Always mix your fuel with an approved fuel stabilizer. Fuel begins to go bad after a few months and that's why many people have fuel problems in the spring.
I hope I've helped. Thank you! Dane
