Problems with Protank 3

[6steelstrings]

I have two pt3s and one of them now has a real right draw. I have taken it apart and checked everything. I have even changed the coil to see if that was it and nothing has helped. I switched the drip tips and that didn't help either. What should I look at now to try and solve this problem?

My other one draws real well.

The best advice I can give is to order the Airflow Control Valve, you can find them for around $5 a piece and they work wonders.

If you tighten it down too tight on your battery, it will compress the little rubber insulator on the bottom of the head, making it swell, and blocking the airflow. You can remove the coil head and gently pull the pin out just a very slight amount, no more than 1/16 inch. Then reinsert the head and try again, this time not tightening it past the point of contact with the center pin on your battery.

This seems to be more common with the new style of heads (which is all there is anymore) since the rubber insulator is softer.
