Check for spark in the new spark plug, if you have spark clean the carb fully and try again. make sure you have correct mix of gas to oil and it is not old use fresh gas oil mixture. Good luck pal.

If you haven't done it already, install a new plug. It's possible you're being fooled by a faulty/fouled plug. A fouled plug may not spark visibly - like if there is dirt down in the recesses of plug around the electrode. It would be a good idea to check it with a new plug before spending $80 bucks for a new ignition module.
