Small Engines (Lawn Mowers, etc.): Lawnmower parts adn illustrations, gas leaks, lawnmower parts

Question
The answers are all great and I know where the gas is leaking the only problem is I don't know the name of all the parts.  Is there a website that will illustrate in a drawing or pictures what are all the parts.  The lawnmower in question was given to me and I cannot find the product name.  The gas leak is coming from the right side from a white cylinder container with a nut on the bottom (I think that's where the gas leaks).  It turns on and runs but then runs out of gas i am assuming and stops.


Answer
 Hello Terry:

 Look on the Metal Engine Cover just Above the Spark Plug are there Any Numbers There? If Not then, Look on each Side of the Metal Engine Cover. You should See some Numbers on that Metal Engine Cover. If you send me All the Numbers off the Engine Cover, I May be Able to Locate an Online Diagram for you. Without Any Numbers I cant be of Assistance. The Cylinder with  the Bolt in the Bottom you are Speaking of is the Carburator. From the Problem you Described, the Carburator Requires Cleaning and Rebuilding. Hope this Helps. Let me know what Happens, Please.

 Good Luck

 Respectfully

 John
