Hellhound mech mod help!

I have just got the hell hound and I can not get the thing to fire! Fiddled with 510 on my hell boy, made sure the screw at the bottom to stop battery rattle was snug, cleaned the hole thing twice! Has anyone has this mod and had the same problems. It’s side firing and I really don’t want to take the firing pin app as it looks so hard! Help!!

Are you sure the center pin of your vaporizer is in contact with the mod? Not familiar with that mod, but my Vanilla has a screw-in-a-screw arrangement to make sure you contact the atty and the battery. A lot of attys these days also have adjustable center pins.
