Question
Model #: 20112X92C - 20" - It has spark to the plug; it wants to start, but doesn't quite make it..... I have replaced the spark plug, cleaned the carburator, made sure it has gas/oil - any suggestions??? Thanks!

Answer
 Hello Cindy:

 Check the Compression. It should be 70psi Minimum. If the Compression is Good, then the Carburetor is Still Dirty. Did you Soak the Carburetor Overnight in Carburetor Cleaner? Did you Blow Out the Carburetor Passages with compressed Air? If Not, then the Carburetor can Still be the Cause of the Problem. Send me the Model Numbers Off the Engine, Please. The Manual and Web Sites for this Mower Do Not Show the Breakdown/IPL for the Engine. With the Engine Model Numbers I can Locate the Proper Manual and Better Assist you. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
