My lawn mower is 15 years old and still starts on the first pull every time. By spending a little time in maintenance, I’ve enjoyed years of service and avoided premature replacement.
This 22″ self-propel mower is powered by a 7-hp engine. Aside from regular maintenance like changing the engine oil and replacing the spark plug, it has also required several minor repairs.
Lawn Mower Leaking Gas
After five seasons, the engine started leaking gas and would not start. A leaking primer bulb was the culprit.
The primer bulb is made of rubber, and will crack from age and sun exposure. Other causes for gas leaking may be a bad float needle or a worn rubber gasket inside the carburetor.
Lawn Mower Won’t Move
The main cause of a self-propel mower not moving is the drive control cable. Other causes are worn or broken drive belt, bad transmission, or broken pulley.
Lawn Mower Hard To Start
Through mechanical wear and use, small gas engines require valve adjustment from time to time. The procedure for adjusting valves on Briggs OHV motors is basically the same for all models.
Lawn Mower Won’t Start
There is no motor easier to diagnose than a Briggs & Stratton lawn mower engine. Presuming nothing is mechanically broken, follow these three steps. Check that the air filter isn’t clogged. Next, check for spark. If you’re getting air and spark, you have a fuel problem.
Sharpen Or Replace Blade
There are several ways to change the oil on a lawn mower, I usually tip it on it’s side. While doing this, I’ll clean underneath the deck with a scraper or blunt screwdriver. I’ll also check the blade for sharpness.
The first time my lawn mower blade needed sharpening, I bought a new blade. Now I have a spare that can be sharpened and ready for next time.
Lawn Mower Service Tips
Always make sure the fuel is fresh (not six months old). The #1 problem that small engine repair shops have with lawn equipment is issues from bad or stale gas.
