I have come to the conclusion after multiple washes that its something in the plastic, either the insulator for the pos pin, or the plastic used for the top. It has a very strong burnt smell. You can smell it even after its been washed and dried thoroughly. I will keep in mind the coil contacts, however I do believe the issue is not with how I build it, as I tried multiple times with single coils. The plastic isn't burnt, as I never used it long enough to do any damage. Took maybe a few pulls and it was noticed immediately. Thanks for all the feedback, I guess at this point its just going to be a paper weight. I can't see vaping on something that taste like burnt rubber. Its a shame because I really like the look and easy of building on it. Thanks everyone.
