Title: Carb question
Post by: Crunchy on May 03, 2017, 04:40:25 PM: So my lawn edger has been giving me fits. Relatively new. It starts up fine. After running for about 2 minutes the carb starts acting as if the choke is pulled, and begins to pukes gas, and dies. I noticed today that shortly after it did this I unscrewed the gas cap and air rushed in. So I don't know where to begin to look. I have torn the carb apart twice and cleaned it with carb cleaner. Just cant seem to figure out if the vacuum issue is the issue, or the carb is causing the vacuum issue. If I cant figure it out, I will check on line to try and buy a new carb and see if that fixes it. ideas?

if you get a new carb,get a good one not that china crap..

sounds like you worked around the problem. most small power equipment has a 1 way vent built into the gas cap, to let air in but not out. often times they'll fail and seal up tight, so once you start drawing a vacuum in the tank the carb starves for fuel.
