I can't get it to fire in 18350 mode. I got two new efest batteries today and charged them up. The charger says they are at 4.2 volts so I know they are good. I have sanded my contacts so do you think the bottom contact isn't reaching the battery and maybe I should take some metal off the bottom of the silver telescopic tube. Only thing I can think of is the mod is bottoming itself out and not reaching the batteries.

They are flat tops. Everything is tight. I metered the batteries and they are good. I took some metal off the silver tube and sanded the plastic on the spring a little too. It is making contact I can see where it touched on the battery. The crappy 18350 that came with the kit wouldn't fire either when I got it so I threw it out. But it works fine with flat top 18500. I am super confused about this.
