I’ve got a Weber 32/36 dgev carb that I bought new a few years ago. It has the Weber logo cast on the body. The center of the gasket surface on the lid of the carb has a slight ridge running around it. The ridge is broken in a couple spots and might be enough to stop the gasket from sealing. I’m wondering if I should file it smooth or if the ridge is there for a reason. ---

I would leave it alone. You have a 50/50 chance of wrecking the Weber. Use a thicker rubber gasket if it won’t seal. ---

Are you talking about the mating surface for the gasket that seals the top to the main body of the carb? I wouldn’t do anything to it, they made it that way for a reason. ![](https://global.discourse-cdn.com/cartalk/original/2X/f/f32d6503c5a6d62bead3afdc1c0856b09598adc8.jpg) ---

Those ridges are there for a reason, to aid in sealing and retaining the gasket. Never file on a gasket surface regardless. The most aggressive approach should be something like a scotchbrite pad to just remove the remaining gasket and sealer if used. ---

Yeah it’s on the bottom of the lid where it meets the carb body. The reason I asked is because the ridge is uneven in spots and I thought it might be a casting flaw. Really though it’s probably small enough that the gasket is sealing around it. Thanks for the replys. ---

Typically, you’ll see those cast in lines along the longer or narrower stretches of the sealing surface to keep the gasket from moving out/in and stay aligned between the sealing surfaces. The variation in height isn’t critical. That ridge will easily bite into a fiber or rubber gasket to complete the seal.
