Hi Brian, If you contact Nhaler, I'm sure Drew would take care of you with the cartos. We supply the cartos that come with the tank, but Nhaler sells their own pre-punched replacements.
One hole is generally fine. We use two different configurations, but one bigger hole is our norm.
When you say not working.....is it just not firing?
If that is the issue, the carto center pin needs to be pulled outward a hair with tweezers or I use a dental pick.
Anyway, yes I do sell Boge Cartos both punched and unpunched by boxes of 5. To get them as pre-punched, you need to go here to buy the cartos and then choose the size and ohms and the prepunched option.

Pm me and we'll see if we can't get those other cartos working.
