My lawnmower was stored outdoors under a tarp for the winter. I pulled it out, changed the oil, changed the blade, changed the air filter and cleaned it up. It started at the first crank, like always. However, it seems to run slow. When I changed the filter, I found one of the springs was broken. I replaced it but I'm not absolutely certain that I placed the replacement in the correct place. Can anyone provide me with a picture or a diagram of where the springs go?
