    i have an FS 85 that does not have spark. i have changed the plug and have i disconnected the kill switch just in case that was the problem. i have a new coil and will replace it this evening. can someone give me any specifics? i have searched this forum and can only find some generalities about the air gap. does anyone know the specific recommendation? anything else i need to know??????
