my savage was running fine before the winter perfectly, and i took it apart yesterday and made sure the carb was clean. when i tried to start it today. it wouldnt start, i checked the glow plug and everything seemed fine. the gas is spitting out the exhaust so its obviously making it through the engine. i drained the whole roto start battery trying to get it going. the temperature is around -2 degrees Celsius outside. Anyone have any ideas as to what is wrong????
