about one month ago I tried to start my mb up, but it wouldnt start, I didnt really mess with it cause I was in the middle of my last build. a week or so goes by and I tried it again (this day was much warmer) it started right up. the next time I tried it was cold and it didnt start. So today is cold and I tried to start it and to wouldnt, then i brought it inside for about .5 hour and when i took it back out to start it wouldnt but it tried and for about 20 feet it almost did start, actually it did but it smelled real funny. then it died and i dont know what to do.
