Has been unused for 2 years & will not start. have checked spark plug & added fresh fuel. what now>

Hello,
My name is Dane and I am going to help you solve your problem. I believe that you have clogged jets/passages inside of your carburetor. This can happen when an engine gets little use, allowing the fuel in the system to get old and begin breaking down. If fuel is left in a carburetor for more than a year, it can eventually turn into a jelly like consistency, and clog the fuel system. The other way to block these passages is to allow dirt or other debris to enter the fuel tank. This will be picked up through the fuel line, also clogging the system. The symptoms can be anywhere from a slight miss, to the engine not running at all. Always check your spark plug first before starting any troubleshooting procedures on an ignition system. Clean or replace it if it appears fouled, burnt or otherwise unserviceable.
The easiest way to determine if you have a clogged fuel system is to remove the air cleaner/filter, and spray a little starting fluid directly into the carburetor opening, and crank the engine. Do not use a large amount of starting fluid. Using too much starting fluid can harm your engine. If it starts for a couple of seconds and then quits, you’ve found your problem, a clogged carburetor. If not, you have another problem.
Before you begin the task of cleaning your Carburetor, you may want to consider just buying a new one. They aren’t that expensive and after 2 years of sitting, yours will be very hard to get properly cleaned. Your choice..
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. Check the air filter and make sure it’s clean and not oil soaked. Replace if needed. If you suspect your fuel was contaminated or old you should also drain, and flush your fuel tank. Dispose of your old fuel properly.
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
