Fuel,air,and spark are the three things that you want to check for first.
If you can get a cap of fuel mix down the throat of the carburetor, if it starts then dies its a fuel related problem. If it doesn't start its probably a spark related problem.
Compression is also required for starting in 2 stroke motors, so pull the muffler off and inspect the piston.

Just a few questions... did it run before storage? Did you replace the coil just because, or was there an issue? Do you still have the original coil?
Why the coil did it have no spark ? Does it have spark now? Might be the carb since it sat for a while. See if you have spark and if so put a tiny bit of gas in the carb throat with throttle open and see it it fires momentarily.
Right there with ya bud. Those coils are pretty robust, but it would be easy to set up a new coil in the wrong spot.

Should have spent half the money on an 066.
