We run 32:1 in our 2 stroke stuff. Which is mainly just chainsaws, weed eaters, and my little 60cc snowmobile. But if you havent checked the spark yet, its really simple. I did it on my little snowmobile. I just unscrewed the plug with the cap still on it, held the tip against a cooling fin, and pulled it over. But, make sure you dont get bit by it. Which is basically getting zapped. I was a idiot and held my finger on the tip, and i found out in a instant it had spark.
