94 indy classic

New to site and looking for some help diagnosing my problem. Sled abrubtly stopped running. Up until that time it ran great. Only have about 4000 miles on the sled. Here's my problem.

I have replaced the CDI box, both carburators have been removed, torn down and cleaned. I suspected that fuel had gone bad which is why I have cleaned the carbs. Fuel was coming out of the vent lines and plugs foul easily. Is there any other direction I can go, such as timing, reed valves etc. that may be causing a problem. Last attempt at starting it did cough back through the carbs but did not really sound as though it wanted to fire off. Any help tracing down another possible avenue to take that may be contributing to the no start problem would be greatly appreciated.
