Hello im so confused on to what i need to do to get this working i am using the KTS storm flat top model with panasonic cgr18650cg bats. when i get everything screwed in and tightened it doesn't want to fire but once i loosen it up a bit it works, of course i don't like that because the mod jiggles around. ive read some forums that say to sand down both positive and negative posts because they are chrome plated but also read that i should remove the spring as well, please inform me on what i need to do to get this working properly.
