Ignore those who prattle on about spark plugs. Should not prevent it from starting, especially if they were alright before! If they are dry there is no fuel getting to the cylinders - carb problem, air leak, a valve, or more, set too tight or damaged.

Try cranking while spraying carb cleaner or starting aid into the carb inlet. If it fires you will know for sure it is the fuel system.
