Check out the GG subforum there may be more people there using carto tanks on the GGTS that may be able to help.
That being said can you give me a little more info on how you are using it? Are you using adapters or did you take off the over flow tank. If you are using adapters which ones. Have you tried it without the adapters and overflow tank? How open is your draw controll? What kind of juice are you using (PG/VG ratio).
I know that is a lot of questions but as I understand carto tanks the juice is drawn into the carto by the suction when you take a hit. All of the above questions can hinder your draw which would in turn suck more juice into the carto from the tank. For example if you closed the draw controll completely or covered the draw holes and took a puff you would likely end up flooding your carto and or with a mouthfull of juice.
Are you using adapters or did you take off the over flow tank. If you are using adapters which ones.
Yes I am. I'm using 510 to 901 and 901 to 510 adapter
Have you tried it without the adapters and overflow tank?
nope, but will try. I will admit I greatly dislike the way my ggts looks without the top portion of it being on.
How open is your draw controll?
Fully open.
What kind of juice are you using (PG/VG ratio).
I'm using a juice that a local guy makes. Unsure of the pg/vg ratios
