I haven't used my lawn mower for years. Did some work on it and finally got it to start again. However, it was running way too fast. Looking at the governor spring, I realize it only had one spring. The motors I have seen so far always had two. However, I didn't really see where the second spring could hook on to and how could a spring get lost anyways. So does my 1995 Briggs and Stratton HD3520A only have one spring? Everything seems to move pretty freely so I don't think it's running fast because something is stuck. PS: I tried to find the engine model number and checked all three proposed locations but couldn't find it. Either it rusted away or they didn't print engine models back in 1995.
