Looks to be a tab for possibly holding the lamination layers together? There's another one adjacent to the top mounting hole. (I was hoping for a hidden timing adjustment feature.) LOL
Still waiting for the tank to completely dry out before fueling back up and trying to start the beast. Had to repeatedly flush it with water to get rid of all the debris. Was a pretty nasty layer of tar and gravel in the bottom even though the fuel that was in it was nice and clean. Don't think much was making it through this filter. Makes me want to revisit the carb for a closer look there, too.
