I can tell you what the problem is. Yes, your coils are too big, and one of them is touching something. The Goblin has a really small deck. I didn't read the first post well to see if you were using an RTA.
Is 26 all you have? Try 8 wraps for a better fit. If you want a higher resistance, try 28g.
Make sure you check the resistance both before and after you put the chimney on. If it changes, you need to get those coils positioned right so they aren't touching the chimney.
