Occasional burnt hit off protank?

[JasonK94Z]

I don't know why, but my protank after 5 days gave me a couple of burnt hits this morning. I'm running it at 4 volts on my smoktech winder with some mt baker 80/20. Any ideas? I haven't gotten that with any of my 50/50 stuff or from any other clearomizer from Kanger. The protank has the 2.5 ohm coil that came with it.

i usually tilt my protank so the air bubble hits the wicks to promote wicking and it goes away. but this only happens on my protank, not my kamry xp or my anyvape BCC.

When this happens to me I just take the coil out of the base. Give it a good rinse with hot water, fluff the wicks up a bit and put it back in. Usually fixes the problem for me. I assume the wick is getting gunked up and the hot water rinse usually fixes it. Protank coils are cheap, so if that do not help just put a new coil on it. For 100% or high VG juices I find I need to remove one flavor wick on a brand new coil to avoid dry hits.
