Step 7: Troubleshooting
-If your flamethrower isn't spraying then check the blue piece under the can and make sure it's attached on all four sides.
-If the flame doesn't reach high enough to light the spray then change the angle of the lighter or find a different lighter.
NOTE May need to be adjusted based on the size of your lighter and spray can (mosquito spray, body spray).
