UPDATE: PROBLEM FOUND
I decided again last night to take a look at my Reo since I was still not getting a good connection and it was arcing bad(looked like a sparkler show). Had to keep turning the battery in order to get a little vape from it.
This is going to be lengthy: So once again I took the tube off, tightened the tube connector while holding a flat head to the 510 pin. Put tube back on, put some glue between the tube on top of firing pin and pushed tube up flush against pin. Tried again, still had to keep turning the battery, so put a new battery in, same thing.
Opened her up again, took bottle off, took delring block off, then saw that there was liquid lurking in-between that sleeve on the firing pin.
So I took the pliers and pulled that connector off from the 510 pin since it would not turn, took out the 510 pin and that little white plastic ring. Then I wiggled the rubber gasket out, rinsed the whole thing under hot water, dried it all out, took a q-tip with alcohol and wiped it all out. Went for a detailed inspection lookie round. Went to my fix kit that I had ordered when I bought the reo. Took a new white plastic ring, new tube, new 510 pin and new connector pin. Before attaching anything I took another look.
Welllll, I discovered that on the inside of the mod right under the 510 threads there is clear rubber around the bottom of the 510 and that was partially missing so the e-juice is leaking from there onto the firing pin.
So before you waste two firing pins, the white plastic round thing, a 510 pin, two tubes, have black pits on four batteries, take a closer, a real close look. Just glad I was able to find the problem.
