Last year my float was stuck open so my wheeler was dumping gas. This year it started to dump gas again so I assumed it was the same thing, but when I removed the carb to clean it again I realized that it was just a few cracked lines. I put new lines on the carb and now when I fire it up it just revs up. If I push the black thing on the left side of the card it idles down for a second but I cannot figure out what the heck is going on. I sprayed carb cleaner on the vacuum hoses to see if there is a leak but nothing happened. Do I have the vacuum lines hooked up wrong?
