First cook - Temp to high
Did my first cook yesterday and had problems keeping the temp down - even with vents barely cracked it (less that 1/8 turn) would run up to 400.
Getting smoke and heat from around the main seal so I tighten the latch this AM - will test again today. I believe I was getting a draft around the main from the loose latch and causing the temp to stay up.
Also, this AM I took a 2 inch SS bolt ($1.25) and slipped/twisted it into a piece of stove gasket I bought ($4.00 at H. Depot). Slide/twist the gasket covered bolt into the roto hole on the right side - it gives a firm fit ...but still easy to remove. Fits flush and flat and with a round top bolt head does not present a problem of catching on anything.
No nut is need and would interfere with the top grill anyway. This should cut down on 95% of the air flowing through that hole. .... So I got that going for me - LOL
You could put a small bit of high temp adhesive on the bolt before you push/twist on the gasket - but let that cure before you put it into the hole!!! Do not think it is necessary from what I am seeing however.
Hopefully this will let me go lower and slower today.
Try this, get only a couple of pieces of charcoal lit (if you are using gas attachment, use no more than 2 minutes). Close the bottom damper completely, then open the low airflow vent to where a quarter would slip in the crack. Then close the top damper completely and open back up the tiniest amount; put your hand around it, when you can feel heat coming out, that is good (you might not even see a crack). Then once you get the grill up to 220 or so, adjust to your desired temp from there.
Now if you wanted a high temp cook, you would lite more lump or use the gas attachment for about 5 minutes or longer. And of course your dampers would be open full. But it sounds like you are having no problems at high temps.
