hi new to the forum,i recently just bought a 99 wolverine 350,the quad is in excellent shape for its age with the original tires still with good tread,the previous owner experienced the same issue i am now,he put a new coil on it about a year ago,i rode the quad all day thursday with no problems,shut it on and off multiple times but i went to start it today and it wont fire,it turns over but doesnt have spark,anybody experience a problem like this?
