Small Engines (Lawn Mowers, etc.): Sears Gas Edger - Spark Gap-Manual, spark plug gap, gas edger

Question
I have a Sears 3.0 hp gas edger. I need to know the spark plug gap dimension and also am wondering where I can find a manual for it.

The model is #536.797522 (code#205502939). I assume it is a Tecumseh engine because the air filter is Tecumseh. I cannot find any name or # on the engine housing.There is a number stamped next to the engine (143 824012 ser20368)but I do not recognize this as an engine number.The current spark plug in it is a Delco R45.

In regards to a manual for it, I have looked at www.outdoordistributors.com for the manual and they do not have one for it. Are there any other avenues I can take in order to possibly obtain one?
Thank you in advance for your cooperation.

Hello Thom:

Yes this is a Tecumseh Engine (Model 143.824012). The Plug is Usually Gapped at .030in - .035in. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.outdoordistributors.com/ and Select the T. Then Select Tecumseh. Then Select Don't have Part Numbers. Then Enter the Model Numbers. Then Select your Model and Download the File for Online Viewing. Since this is a Tecumseh Engine, I have a PDF Site Addy that May Assist you Also. http://www.tecumsehpower.com/CustomerService/BSI.pdf You can Purchase a Service Manual (TEC-740049) from Outdoor Distributors for $9.22us Plus Shipping.
