Ok, I need some input. I just bought a Kawisaki KBL26A trimmer about 3 weeks ago. It is a good trimmer except it "stalls" at low rpm. It idles fine, but if I try to hold the throttle low it just stalls out, but if I give it more gas it is fine. At first I thought it was new so it would run better after a few tanks, but is still doing it. It's really aggravating, but other than that it runs great. Any input is appreciated, thanks.
