Others are a whole lot better at this than me, but do you have spark? Disconnect a spark plug wire, pull back the rubber collar, hold the metal end near the block, have someone try to start it and see if a spark will jumps to the block.
Is the carb getting fuel? The old way would have you disconnect the line from the carb, put the end in a bucket and have someone crank the starter with the coil wire disconnected. You don't want it starting, but I guess that's the original problem! Stop cranking as soon as any gas shows up in the bucket. There's potential fire hazard here so maybe someone has a better way.
If it has spark and fuel, it must start, right?
