I have a 1994 Artic Cat ZR580 and 2 days ago i bought and changed the spark plugs that night it took about 30 minutes for it to start up, the next day i tried starting it up and it took me about an hour and half of pulling to start it up. Today i tried it again and it wouldnt start at all ive been pulling for along time and my friend had me check the spark plugs to see if they where wet and they where, then i tried to see if there was a spark and there wasnt, then he had me put a little bit of gas down the spark plug holes and it wouldnt start, i checked that the key was in the kill off and im going on a trip this weekend, my friend thinks it might be a bad coil? Please Help!!
