Hello I have a Briggs and Stratton 32000 series that has been recently rebuilt. (new piston/rings) It runs amazing except for a small tick coming from the engine. The tick is very soft and I can't hear it and once revved up it only is noticeable at idle. It does not seem to be coming from the valves, but I could be wrong. I am not really worried about it because it is not very loud. Is this just something these older Briggs and Stratton engines do or should I be worried. I would show you a video, but the mic won't pick it up. Any help/suggestions would be greatly appreciated. Thanks all!
