jerry the bowman is a very good lighter. is there a little collar with a notch in it around the fill nozzle on the bottom? that is the flame adjuster. you need a little screwdriver to turn it.
i find with my torches that you need to fill it 2 or 3 times, 10 or so secs apart. apparently the can doesnt exert enough pressure to fill the lighter all at once. have read on other boards that you can hold the 'light' switch down when you fill the lighter, allowing the new gas to push out the air thats in the fuel tank. do NOT do this if there is a flame coming out of the lighter!
hope this helps!
