I've been vaping my claptons I put in last week and they've been putting out great flavor! Today my tank ran low so I opened it up and tightened down my posts because my ohms were jumping from .3 to .4. This seemed to fix the problem. I'd been vaping at 41.5 watts as that's where I found my preferred vape. Well after putting it back together and refilling the tank I took a hit and it was burnt. I kept turning it down til 30 where I can take a couple Vapes but can no longer chain vape without getting that burnt taste. Please help! Do I need new coils already??
