ask some one for there plugs, and try them out yours might be dust..anpother thing ur distm might be fed up so thats another thing to look in to. Pull out one spulgwire with a spark plug in the cap, hold it with some pliers and aim the sp[ark at your valvecover bolt or some kind of ground (about 1/2inch in distance) and have someone turn overe your motor if there is truly no spark it wont send a spark to the ground...
