The 8 is a fully rebuildable mechanical mod. Have you tried disassembling it and reassembling it? It comes with great instructions, this video from @THC SCIENTIFIC will help ya out too:Hello. I can't get my 8 top to fire hot enough for my Herc.
Any other suggestions please? I really want to use the 8 top with the 8 body instead of my hammer top.
Thanks and enjoy.
The key when doing so, is an adjustment in the flathead contact screw behind the button. If that screw is not in the right spot then it won't make contact with the top and bottom pin equally. Check this by seeing if the Hercules heats more quickly if you jam the button upwards slightly. The contact screw usually doesn't need to be jammed hard against the threads bottoming. Try backing it out a tiny amount and adjusting it 1/8th of a turn counter clockwise at a time.
If you have an early 8, there is also an upgraded button assembly that I keep forgetting to order. I better do that tomorrow.
