@mirkwood ...it may be your startup. Only drop about 10 hot briquettes lit in the middle. Top vent fully open. Only use one vent ever slightly open. Warmup for an hr. She should run steady around 200-225..if too low..then adjust slightly on another bottom vent. Slight adjustments in 70 degree weather willbheat her up..once a wsm fires up hot..its hard to pull it back...easier to raise temp than lower
Toolhead, I think the last time I cooked on it I may have used 12~15 lit, all vents were open full
until the temp was around 190 on my Maverick ET-733 then I closed them all down to about an
1/8 of an inch. It then took another 30 minutes to get to 225 and I was thinking great it’s going
to settle in and play nice, which it did for about 20 minutes and then it did it’s spike thing and
was essentially, outta control till the temp tanked at the 4 hour mark. I closed all the vents
down when it spiked and it still behaved like a Doberman on LSD till the fire flat lined..
