Try another plug first, and the back ones are easy anyways. If that fires, time to start looking for a stuck float maybe??

Yah! find a spare plug, pull the wire and hook it up to the plug. Rest the plug against any good ground, turn the key and crank the engine and see if you have spark at all.

 

I'm betting it's carbeuration problems. A half can of seafoam into a tank of gas and a good ride may bring things back to normal. Plan on changing plugs after the seafoam treatment as it will loosen a lot of crud! Yes, you can put the whole can in but plan on seeing a lot of smoke...

I put sea foam in tank before storage in the fall then when tank runs out put more in will get a plug and try turn starter over and look for spark
