Keeping temp below 300 problems

I am having problem keeping the temp below 300. I had no problems for a long time (the first year I owned my Egg) then I replaced my gasket and the egg always wants to stay around 285 or higher. It passes the dollar bill test and the vents are nearly closed (pics below). The only thing I can think is that I need to clear out the silicon around the draft door and re-caulk since it seems to be degrading and cracking and maybe that is letting air in. Let me know what you think. Thanks for the help in advance!

    How much lump are you lighting and how long are you letting it preheat for?

    Full load of lump. I have ribs on. Let it creep up to about 265 and stabilized it. Put on the meat and once the meat came to temp the Egg crept to 300. Has been happening since I changed the gasket. It's odd since the first 100 low and slows I had no issues and now that I changed the gasket it is giving me some trouble.

    I'm stumped. I would try lighting at fewer places? and shut it down sooner? seems weird because it seems as though you have a winning combo aside from the temp creep.

    Have you confirmed your thermometer readings? Also when vents are closed off that much are you seeing smoke come out anywhere it isn't supposed to?

    how long has the temp been creeping? maybe it just needs time to ramp down. How long did you let it stabilize?

    But does it creep back down, after the meat reaches temperature?  Mine does the same thing, stabilized at 225, load the meat in, drops to 210, then as the meat gets hot it starts creeping up as high as 275 (which isn't hurting the cook) . but then VERY slowly returns to 225 -- like three hours later.

    Seems to me even with a badly sealed lower vent, you should be able to hold lower temps using the DFMT, close it some more.

    On low and slows I only light in one spot in the middle. I usually let it stabilize for 45 or so minutes. No smoke coming from anywhere it shouldn't be. I am stumped also. However, I just pulled off some sausage that was on so now there are only 3 racks of ribs and temp has dropped to about 265.

    If(?) you have a serious air leakage problem, you would have NO lump left after every cook ??

    My xl couldn't pass a "deck of cards test" and has no gasket.

    You need to light less lump. Plain and simple.
    Be careful, man! I've got a beverage here.
