Like title says, I'm new so Hello everybody. The rerason I'm here is I have a 04 LTZ 400, that is driving me crazy. It runs, til it stalls, won't restart, sometimes it just crancks and won't start at all. the way it stalls leeds me to belive it's ingnition related, but it also has me second and third guessing myself. I repalced the coil and plug, cleaned the tank, carb is getting fuel. sometimes it even back fire thu the carb. I'm at a loss. can anyone offer any ideas?
