I did a slow and low test run last night using the snake method. The kettle is out of round and the lid is out of level, but it held temp just fine. I did put two binder clips on it which resolved the out of level issue. With both the kettle and the lid being out of whack I fear that if I try to get both of them back into shape I am just going to screw it up even more, so I am going to leave it for now. Hopefully I won't regret that decision tomorrow or Sunday when I do a pork shoulder. The bottom vents are pretty loose as well, which for an old grill is probably better than stuck vents, but they seemed to still do their job. I can probably slide a credit card between the kettle and the vent on two of them without it touching anything. I am debating removing them so I can really polish them up, but I am not sure if I should do that or leave them alone since the vents and the rivets are still original.
