Small Engines (Lawn Mowers, etc.): Tecumseh, oil drain plug, snow thrower

Question
I have a year old Troy-Bilt 2 stage snow thrower with a Tecumseh #LH195SP 4-cycle engine. I need to change the oil and cannot determine which plug is the oil drain. The manual is pretty vague. Any help would be greatly appreciated.

Answer
Typically the oil drain plug on a snow thrower engine points to the right or left side.  Some snow throwers will have a small pipe running from the oil drain hole to the side of the frame.  It is usually in the lowest rt of the crankcase.  The ones I have seen have a square head.
