It's a new kit that I used once about 6 months ago. It worked fine. I tried using it again lately and the flame doesn't stay on. With the slightest breeze or whenever I move it on an angle the flame goes out. Sometimes it's difficult to ignite.
The tank is 3/4 full, and I checked 10 times for any debris in the nozzle but it's clean. It's a standard manual nozzle (not with the auto ignite) and I don't see any air/fuel ratio adjustments.
Also, when I ignite it with the sparker the flame will go out as soon as I move the sparker away from the tip, but if I leave it about an inch from the tip the flame will stay on.
What could be the problem?
