I got my first Russian several days ago (new) and set it up with a 1.7ohm coil and cotton wick. It worked perfectly the next day however my resistance kept creeping up until it was 4.1ohms. I was driving so I put it down for a bit and it came down vaped it again and it crept up to 3.8. Put it down it went down again finally it stayed up around 3.4ohms. So I figured it was my coil 30g kanthal 5 wraps. I took it apart there was nothing visible except 1 side of the cotton was darker (more liquid not burned). Nothing was touching and I assume it was not shorting as I have it on a lavatube so it has a shut off. I rebuilt the coil replaced cleaned everything and now after several hours it is happening again. Anybody have any ideas? Thanks for the help in advance.
