I sat here typing out that last post whilst the wife was changing to a different juice in her Mini PT2. First it won't feed so I give it a whirl and get it to feed but only by pulling really hard without firing then firing it. Funny, she switched from a 10/90 mix to a 50/50 (much thinner). So I grab a coil that I had rebuilt for my PT2 which was working perfectly in it and FLOOD!!! (that was almost an hour ago and I'm still tasting the $$$$). Now I grab a new, never used coil and it's back to working perfectly.
Tried both coils in my PT2 with a 50/50 and both work perfectly. I don't get it.
Okay, dumb question. Did your wife let it sit and absorb the new juice into the wick first? If not, it's possible that the 10/90 thick juice was still on the wick and keeping it from feeding, then by forcing it you caused it to over-feed. Just a thought, HTH!
