Well I used the video that was posted on punching your own cartos, and so far no leaks. I'll keep my fingers crossed :) When comparing the holes, they are much smaller then the ones I purchased.

Curious xanas.. did you punch 1 hole or 2 holes? I went and found the 1/4" self-tapping saddle valve myself (LoweS), but have yet to try it. Thinking when I do punch cartos, I'll go with 2 holes.. unless I run into problems.

Seems like such an easy and great tip!

i've found that it varies from carto to carto, even from the same box. i always put 1 hole in a Dual Coil, but some cartos seem to leak no matter how small the hole, and others seem to need a larger hole to properly feed. i've found a good middle ground that seems to work well with most DCs so far.

it also depends on how hard you pull when hitting your PV. my girlfriend takes harder pulls than I do, and she was sometimes flooding the DC in the tank. so now, i punch her cartos with slightly smaller holes than mine, and we end up getting essentially the same performance from our cartos due to the difference in our draws.

there are 2 factors.

size of holes

absorbency of the carto (at least in the case of DC cartos)

i have had my DCT MAP tank for a while now, and I LOVE IT. there was a little trial and error at the start though.

my first carto that came with it from COV that was pre-punched worked perfect, no leaks, for about 60mls of liquid, then it started to flood out of no where. i chalk this up to the cart being worn out and the absorbency of the filler being lost....i then tossed the carto.

that carto had 2 small holes in it as prepunched from COV.

I then punched my own carto, without realizing it i made the holes just a tad bigger. this carto leaked from the start almost. after the 2nd or 3rd fill it was leaky a bit....i figured the holes were too big, i tossed it.

now i am making 1 small hole in my cartos, they are working great, and i am getting roughly 60mls through each before i punch a new one which i think is an acceptable rate.

my single hole looks like the cart on the right here*

HTH

tldr. if your carto leaks from the start, holes are too big, if your cartos starts leaking after a few fills, its lost its absorbency.

*to punch mine i
mark the level the hole should be at with a sharpie marker compared to my original DC from COV, then on the kitchen counter I, crumple a paper towel, place the carto on it, hold a small/finish nail where i want my hole and tap with a hammer.

i just picked up one of those saddle vavles, and i think it is easily the best $7 i've spent on vaing. super easy, consistent carto punching, with minimal denting. I was able to screw the tap in all they way in order to get the slightly larger diameter hole that i like, without puncturing the center tube.

i thought the carto on the carpet with a hammer and nail was easy enough. i was wrong.
 
I just got a M1A1 with my new Buzz Pro and a new Dremel. I had no problems destroying 4 cartos but was unsuccessful at using the tank. The BP has a tight draw with the 510 cap so that didnt help matters. I am going to get a 510-510 adapter (for better airflow) and the 1/4 inch punch. This sounds like the working combination. Thank god I saved my Dremel receipt!

I have the same issue. I freaking love, Love, LOVE my MAP and CoV. I too followed that same video and when I pull the carto down to expose the holes, that's when it leaks like a sieve. I punched my own holes (2) (the hole that came with the cartos were too low and too small) and I also think i made them too big.

Other than that, love my MAP and am stoked that I bought one.

OK, to be honest, I am not loving the MAP so much now. I just refilled it and liquid started flooding out the bottom as I was filling. I lost about half a tank full by the time it was pushed all the way down the carto. Then, when I went to take a drag, all I got was a mouthfull of ejuice. Now my throat is burning, I am buzzing horribly, and I have a headache.

Never thought I'd say this but I am missing my eGo tank.
