Try starting the engine, pull the spark plug out and see if it is wet with gas, if it is you might not have any spark(possible from a fouled spark plug) or it might have low compression, put the plug into the spark plug boot and set the tip of the plug onto something that is metal on the engine and turn the engine over. you should see spark, no spark=ignition problem.
