Update,
Changed atomizers and I placed the dewicked/debridged 510 atomizer from avidvaper on my Reo and the burnt taste will not go away. I dripped on it and it will be good for one pull but after that it goes back to the burnt taste. I pushed the bottle and I see the juice coming up but it never reaches the coil unless I press really hard. Should I just throw the 510 atomizer out?
Since I'm having trouble with the 510, I decided to put on a new 306 and I noticed that the mesh and bridge is bent to one side a little bit. I pressed the button but it won't fire up. Today is not my lucky day haha.
Edit: Using the dewicked LR 306 cisco atomizer and it is smooth.
I had the same thing happen and then realised that the tubing was resting against the wall of the bottle and couldn't draw the juice up. Readjusted the bottle and it worked fine. Hope it's as simple a cure as mine was.
