Filling cartos before punching

[skoot]

One of those happy accidents, I forgot to punch my carto before I filled it for a tank. I figured juice would flow out the holes and make a huge mess. Actually it didn't, at all. I found it MUCH easier to fill the carto first, then punch and insert into the tank. It's a lot easier to manage the carto with a toothpick shoved in the blowhole when it's not in a tank.

Yep. I've been doing this for a while. Just easier to me this way.

That is the only way I do it...I also test it to make sure it fires up before putting it in a tank.
