This is my first smoke with new WSM. I'm having trouble getting the heat high enough (even with bottom vents wide open, I can't get much over 200). Most temp issues I've seen involve it being to high. A quick review of what I did.... anyone see an issue? Used chimney starter to get approximate 100 charcoal briquettes lit. I may have let them go too long as about half were all white when I put them in the WSM. What's the best way to increase heat? What's the best way to add lit briquettes to the running WSM. Thank you for any advice!
