I would like to have a manual so I can service the mower I just acquired. Also, this mower has a gas cap that has a "stick" on it giving oil/gas mix. I'm sure this is a 4 cycle engine, but I did mix oil with a small amount of gas in order to get it started. Another question relates to how do you check hydrostatic fluid, I have only found the "fill' tube?? Thank You, Gary
