Small Engines (Lawn Mowers, etc.): Fouled Plugs 18 hp Kaw, carburator, leet

Question
John, On 8-15 you responded to my question about fouled plugs for 18 hp Kaw.  You asked for the moldel numbers of the engine.  Following is what I found.  code-FD501V-AS00  and E/No FD501V012955.  I also said it was an 18 hp when it is an 17 hp.  Does this change your response?  

Answer
 Hello Mike:

 According to Kawasaki the Engine you have is a SSO(Self- Servicing OEM). I cannot get Any Information on this Engine. If the Carburator has Mixture Screws, these can be Adjusted to Lean the Carburator. Hope this Helps. Leet me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
