In my 30 years of professional repair experience I have watched the face of the lawn equipment industry change drastically. From the first zero turn mower to the recent If you have ever experienced a time when your lawn mower runs poorly with a lack of power, try this little trick.
ACTION= With the engine running, slowly begin putting the choke on.
THE RESULT WILL BE ONE OF THESE 3=
- The engine runs better.
- The engine runs worse.
- No difference.
DECODING THE RESULT=
- Your lawn mower engine starts to run better = FUEL ISSUE. When you engage the choke lever you are limiting the air intake to compensate for the lack of fuel. Look for problems ranging from a fuel restriction to an internal issue in the carburetor.
- The mower runs worse= IGNITION PROBLEM. Why? Because You just added extra fuel to an already weak spark condition. Start by simply installing a new set of spark plug(s) and have a competent mechanic test the ignition system with the proper diagnostic tools.
- There was no difference= MECHANICAL ISSUE. The problem may be an air leak, a compression or timing issue. Possibly a combination of all the above. This one is best left to the professionals.
Make sure you choose a professional repair shop that is a certified dealer for your engine brand. That way, You’ll have recourse if the problem returns.
