I've only had the burnt taste once in 2 weeks of using my 510. I found out the cartridge was just about dry, so I filled it, dripped a couple drops on the atomizer, and presto, burnt taste gone.
One thing I've found is that the slower I draw on the mouthpiece the better the vapor. That, and don't violate the 5-second limit when using a manual battery, because I think holding the button longer than 5 seconds makes the little coil heat up too much.
I've only cleaned one atomizer, by blowing through it from the end that connects to the battery and then standing it on a paper towel and letting it drain. It works no better than my other atomizer that I've never cleaned. They both work great.
Another thing I've found is that if the battery is fully charged and I'm still getting weak vapor, if I drip a couple drops of VG (80/20 with distilled water) on the atomizer it seems to re-prime it and it's back in action.
