Answer
Stop working on this machine right now and do not touch it until you get the correct information & knowledge to fix it properly. An online motorcycle repair course like http://www.dansmc.com/MC_repaircourse.htm will get you started.

You also need to find a shop manual for this model. It will have the appropriate information about testing the stator and adjusting the carb. You should never attempt any repairs, no matter how simple, without reading the section in the shop manual first.

If you have spark and the engine isn't starting the problem is probably in the fuel system, not the stator.

Is fuel getting to the carb? Most carbs have a drain screw on the float bowl - you can tell if fuel is getting there by briefly opening the drain - if fuel doesn't come out the problem is either the petcock, the filter (if it doesn't have an inline filter it will probably have one in the tank or petcock) or the float valve.

If there is fuel in the float bowl and you have spark, look at the spark plug immediately after attempting to start it. If the plug is wet you have flooding, which probably (but not always) means that the float is too high, the float valve is not closing properly or you have damaged the float valve seat with the wire.
If the plug is dry you probably have a blocked jet or passage in the carb and need to clean the carb properly. This means removing any brass parts (jets &c) that are designed to come out (see your shop manual) and soaking the carb in a metal pan of gently boiling distilled water for about 20 minutes (best done outside - it can smell pretty nasty) and then spraying carb cleaner through every passage, followed by compressed air.

Pushing a wire through any jets or passages in the carb should be considered an absolute last resort. A sharp end on the wire can scratch the inside of the jet or passage and alter the precise metering it is designed to perform. The wire can also force any dirt or varnish into a place where you will not be able to remove it easily and then pack it in there hard.
