i have a Blaster dont no what year it is yet, i gotta call the local Yamaha shop. But i know its an older one. Im haven trouble with it, im new with 2 strokes so. But i got it for 100 ds. and ive got it to run once for me and then it died and wouldnt start again. then the next day my friend took it and rebuilt the carb and he got it to run for awile. i went to his work later that night and it started once and then died when he stoped it and it wouldnt kickover again and it hasnt startd since. it gets fuel and gets spark and gets a 140 compresion but it just wont start. so can some one please help. I am goin to be buyn a new ignition coil on monday to see if that works, cause it may not be getn enough spark.
