I have had this thread over in the tips and tricks area for a while, and it seems to be working well for many people.
I have had many requests to move it over here, so here it is...
The problem with the stock filler is that the top of the filler will get dry when the cart is still half full of juice. That's why you will see so many cart mods out there.
I have tried many cart mods (PTB, ZFM, blue foam, white foam, spring, straw, etc, etc) and they all have their issues.
Here's what I do that works like a charm (for me). Pull out the cart filler and cut about 2/3 of the length off of it. You should be left with a piece that is about a half inch long. Now fill your cart most of the way up with juice (leave it about a quarter inch from the top). Then stick the little piece of filler that you cut right on top and gently push it in until it's flush with the rim of the cart.
This method will not only allow you to get more juice in the cart, but that little piece of filler will stay soaked until the cart is completely dry.
I have been using this method with my 510's for a few months now and have never had issues with flooding or filler taste. The carts will hold about 18 drops and will use every drop before vapor drops off.
Here are some pics of mine. (Sorry about the phone-cam quality. Also, my filler really isn't that brown and burnt looking; I think it is a color thing with my cam.)
Pic showing the plug size and shape relative to the cart. Also the line that I fill the cart to with the juice.
Pic showing what the plug looks like going into the cart. Notice that the bottom is 'pointed' a little. Just kinda ends up that way after 'spreading' the top of it a few times. I spread out the top so it makes a good seal around the cart.
Pic showing the filler before it is inserted into the atty. Flush with top of cart.
Pic after the cart has been put on the atty and allowed the bridge to push the filler to the 'right' spot.
Some other notes based on feedback in the other thread:
- you may have to play with the plug for a bit to get the proper size and density. Basically, if your atty is flooding, make it a little denser and/or longer. If your plug is drying with juice still in the cart, make it shorter and/or less dense.
- the thickness of your juice is going to affect the type of plug you use (but not very much). If your juice is very thick, you may have to make your plug pretty short and loose. If your juice is water thin, you may need a denser/longer plug.
- When I first wrote this tip, it was based on the older style cart filling. I have since noticed that the newer carts are coming with a loose/layered tyoe of filler. If you are starting with this looser/layered type of filler, you may have to compress it a little to make it a little denser.
- I find that just standard (walmart) polyfill is ideal for this method.
