My '95 kettle's vents work fine when it's cold, but when the fire is going, they tend to stick. I thought about spraying Pam on them. What do you guys use?
they might be gunked up. try a good cleaning. many times it just can't be done, so i just take the vents off and then clean. i also replace the hardware with ss nuts and bolts.
one hint. very hard to find ss locking nuts and you can't use locking washers. a trick is to slightly damage the bolt threads. this will let the nuts screw on but it will hold them firmly.
