PIERRE PAGE, you need 4 things for the engine to work, Spark, Air, Fuel and compression. Make sure that you have spark, check the plugs, your ignition coil, and make sure your ignition air cap is set correctly. Make sure your carburetor float is not stuck, that your gasoline is fresh and that the float valve operates properly. Check your fuel filter, make sure it is not clogged, make sure your fuel lines are properly routed and check the jets in your carburetor, for dirt and maladjustments. Check your valves to make sure they are working correctly, set the valve lash as needed. Let us know what you find with further trouble shooting.
A SMALL shot of ether (starting fluid) in the carb will tell you if it's an ignition problem or not. If it fires and dies with the ether, then it's a problem with the fuel system, and not the ignition. If the engine has been sitting unused with fuel in it for and extended period of time, the problem will most likely be in the carb as the crap fuel that we are forced to buy these days with alcohol in it deteriorates quickly and also has a tendency to absorb moisture, which then causes a buildup of deposits in the carb. Once you get it cleaned up and running you need to use a fuel additive if you're going to let it set unused awhile between uses, or run it until it's out of gas. I use Seafoam in all my equipment to keep things clean in the fuel systems.
My power washer was sitting in my garage for two years and I noticed the gasoline turns bad, I emptied the lines I clean up the carburetor and it still does not work. Are use the brake cleaner as a starter it starts ignite and then dies right after to three seconds that tells it has no ignition problem but the problem with the fuel line or field itself I put a new fuel but still not working. If anybody has the idea what else it can be.
My spark plugs are good I cleaned it it was all new,
The brass bolt (bottom of the carb )? or the brass bowl (under the gas tank) ?
Either case, you have a dirty gas tank. Check for 'red' surface rust covering inside the tank.
Vinegar will help clean. Bathroom shower cleaner works very well.
pull the spark plug after trying to start it. It should either be dry or have gas on it. If its dry, the carb problably needs cleaned by soaking it in carb cleaner, and then blowing out every passage way with compressed air. If it wet with gas, try a new plug and see if it fires while holding it on the head, while pulling the starter rope. If it fires, replace the plug and try to restart it.
