Thanks guys I appreciate the help, I'll keep experimenting. I mostly burn fruit flavored juice and that one tank hits way too hard which burns my throat. The other tank I like better because its tastes better and isn't so harsh and doesn't burn my throat but I have to take a really really long drag to get a good hit. Any suggestions on how to get more vapor from this tank? Thank you!
look at the base of the coil unit, in between the contact and the threaded barrel is a gasket, those can get squished out of shape and tend to squish outwards.
Really long drag might be old age, or if this unit has always done this it might be a high resistance coil
The airflow in a protank, T-3 and EVOD flows through tiny holes at the top of the threaded barrel and down the inside of the tube to where the contact is then enters the contact, flows up the pipe, past the coil and eventually gets to you.
Any restriction in any of this will cut off air flow and making you suck like hell to get a hit.
The gasket can deform and mushroom outwards to block the airflow through the threaded body
you can trim the gasket flush with a razor knife or blade, but this will not last forever some PT gaskets are made of extra soft material and will just keep deforming.
The burned taste may come from several things, check the resistance which is micro engraved on the barrel of real Kanger unit If not there, it is not the real deal, toss it as clone PT heads just plain suck all the way around. You might also have burned your wick by firing it without sucking till the wick dried out and then burned.
Ah you are using a spinner so either a 1.8 of 2.2Ω head will do you, but remember thes are made in sweatshops by kids and slaves so you may have one that is way off, only way to tell is put it on an ohm meter.
The only thing I have to say about flooding is when your tank is almost empty, it warms up, point it down or lay it down flat until it cools and flooding probably will not happen.
It's late, I'm tired, I have written thousands of word about protank flooding, sorry but I don't feel like writing it all out again right now but you can do a search for it to learn why.
good night and good luck!
Truthfully as someone who has vaped, rebuilt and run protanks constantly for the most part of a year, the best advise I can give is to ditch them, buy an AGR+ load a Boge LR pre-punched cartomiser into it and see what you were missing for about the same price for the tank and less for replacements.
I now have 1 surviving PT1, 3 PT3s, 4 adapters for Aspire coils, 1 Aspire pyrex vivi-nova, 1 smok pyrex large window tank to fit same and half a dozen coils new in box, official ones for each atomizer and 2 spare PT2 tanks, and I am going to put them all up for sale at 75% internet average and eat the shipping so I can get another AGR+ some batteries and some other stuff, it has been a month and I have not felt like putting juice in a BCC in all that time.
