Can’t get the switch 2 to work properly and consistently

Anyone have tips to on how to properly/best hit this thing? I don’t know why but almost every hit is kinda wispy, leaves residue on my lips/mouthpiece and feels like coats my lungs in resin in a painful almost way where it makes me cough a lot.

Has anyone else ran into these issues and were able to fix it?

Before I was assuming it was simply the glass piece being narrow at the mouth, but now I’m assuming it’s the stock carb cap not allowing enough air to produce decent clouds and instead it’s a mix of air and condensed resin???

Please help!!! Anyone! I’m confused at this point. :/
