Small Engines (Lawn Mowers, etc.): oil plug, oil drain plug, oil mixture

Question
I have inherited a snowflite 8/26 snowblower.
At the bottom of the engine there are several bolts on either side.
which one is the oil plug and does it require an oil mixture?
sorry for dumb question but i couldnt find a simple drawing of the tecumseh 8 hp anywhere
thanks  

Answer
The oil drain plug is the SQUARE shaped plug located in the Middle between the mounting bolts.

Use 5W30 Oil in your crankcase.   You do not need to mix gas and oil.

It is okay to use synthetic oil in your snowblower engine

hope this helps
