Test done and... success !!!
I replaced the spring, keeping the original SS cap and no more heat ! So the original spring itself is resistive
The SS cap have no central plot, so we can't use others Vamos thinner spring in it, I used this spring with a little modification at the base to fit in the Vamo : Indulgence bottom cap
You're awesome man
Even Todd discovers and talks about it during his review: SS VAMO V2 - vapeescape.co.uk - YouTube
Thanks again guys! Wish there was an easy local place to go get a spring at instead of having to order that cap from China. Does anyone know of a US site that has something we can use??? And they charge $17 shipping!!!!
