Small Engines (Lawn Mowers, etc.): Toro S-620 Snowblower, spec numbers, model numbers

Question
I recently inherited my Dad's property.  I found a Toro S-620 snowblower (hasn't been used in over 10 years).  My main question is:  does it take a gas mix, and if so what is the ratio of "what to what"?  I haven't found the users manual anywhere on the property.  Many thanks for this service!!

Answer
Hello Cathy:

>>These Units came with either a 2 Cycle or a 4 Cycle Engine.
>>Send me the Model and Type or Spec Numbers Off the Engine or the Unit/Mower Model Numbers, Please. With these I can Locate the Proper Manual and Better Assist you. The Engine Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. The Unit/Mower Model Numbers are Usually Located Under the Seat on a Sticker on the Body of the Mower.
>>**If you Need Assistance in Locating the Model Numbers, then You can Go to this Site Addy; https://lookup3.toro.com/partdex/default.cfm and Select Step 1.**  
>>Thanks.
