You have most likely done this but lets go back to the basics.
Do you have spark at the plug? Check to see if the plug is fouled - pull the plug connect to the plug wire- ground the metal part of the plug to the metal body of the engine - as you turn the engine over it should fire cleanly from the center to the electrode, if it fires off to the side or has an orange colored spark it is fouled - replace it.
Once we have spark check for gas is it getting to the carb?
90+ % of all small engines not running are due to the fuel line or in tank screen being plugged with garbage. Remove the fuel line from the carb, point it down and using a small container to catch the gas it should flow freely. If you have good gas flow reconnect the fuel line to the carb and put about 1 CC of gas in the plug hole reinstall the plug and fire it - almost all small engines use a bit of vacuum to pull the fuel from the carb into the cylinder, jump starting them with a very small amount of gas directly in to the cylinder can help them get going. A VERY SMALL AMOUNT OF GAS AND CLEAN UP ANY SPILLS BEFORE YOU TRY TO START !! Burning down the house will upset the other half
