You can try spraying some carburetor cleaner into the intake by way of a vacuum line or pcv hose Just a little dab will do you. If the engine tries to start it would indicate that you have a fuel problem.
Any auto parts store sells carb cleaner. If you don't have the skills to disassemble and reassemble your carb you may also want to run some injector cleaner through the gas tank. Also when spraying carb cleaner inside the carb make sure you have the engine running and spray slowly enough so you don't kill the engine. sometimes running the engine at fast idle helps. If it stalls and dies it can be a real bear to get it restarted. Good luck.
Take the air cleaner off and you will see the carburetor bolted to the top center of the engine. That is what the air cleaner set's on. The top of the carb.
