Carb purchase

Save yourself the trouble and buy the new carb first. For 70$ you can’t go wrong. I tried the money saving route with rebuild kit. The time I spent taking carb apart and soaking in cleaner then re building it to discover that the jets must have still had some obstruction. I ordered the mew carb and in 10 minutes had the weed-eater running like a champ. I love the fact that I can order parts for my serial number. That makes you guys awesome.
