Small Engines (Lawn Mowers, etc.): Throttle Control Cable, poulan weedeater, briggs and stratton

Question
The throttle control cable on my neighbor's Electrolux Weed Eater lawn mower (model number 961160003-01) broke and I'm looking to buy a replacement.  It uses a 4.5 hp Briggs and Stratton engine.  The Throttle Controls at Home Depot and Lowes aren't the right kind and I've searched all over the web but to no avail.  Where can I got to find a replacement throttle control cable.  I saw the exact same cable on several models for sale in both Home Depot and Lowes.  Would appreciate any suggestions.

Thanks.

Answer
To find the correct part number you will need the model number of the push mower off of the tag on the frame.  Also the part number is
usually on the black cable itself, in white ink.
   Then google "Milaca Lawn and Garden", and use their free parts lookup, and look under Electrolux or Poulan Weedeater brands and enter the mower's model number, it will give you a complete blowup,
and you can buy the part there, ar sears.com, or any mower shop.
