Answer
Steve, for any engine to run it need the three things you mentioned but you have to have them in the correct amount.  First, make sure the battery is charged.  Check compression..it needs to be at 140 psi or higher.  Check the timing to make sure it's firing at the F mark on the flywheel.  Also you could be getting too much fuel or too little.  If the plug is black it could be fouled and you need a new one. It it starts with a new plug, the carb is running too rich and it's fouling the plug so you'll need to clean and adjust the carbs.
