Briggs & Stratton
Experienced gardeners share their insights in answering this question :
A lawnmower engine has to have 4 things in order for it to operate properly (besides good compression). 1. Clean oil …straight SAE 30 in summer 2. Clean Air (Good Filter) 3. Clean Fuel (no older than 30 days or so) and lastly a strong spark..blue is good, yellow is weak. It may run without these 4 things up to par, but not for long! Start looking around on the mower and try to determine if these things are OK for starters.

Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Q. Why is my lawn mower turning over but not starting? The most likely reason is bad gas. Gas that sits for many months during the off-season will eventually break down, gumming up the fuel line and carburetor in the engine and preventing it from starting.
If your Briggs & Stratton engine has a spark but won`t run, then it is most likely a problem with the gas or air intake in the engine. The spark on the spark plug ignites the gas in the piston, but if the air filter is clogged or the gas can`t flow, then the engine won`t start.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
The buying spree lacked strategic focus and ultimately failed to turn around the company`s decline. Rather than investing in research and innovation, Briggs` management tried to buy success while continuing to enrich its executives and stockholders.

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
Check to see if the switch and terminals are free from rust and replace any damaged or broken spark plugs wires as necessary. Alternatively, it could be a bad ignition module. A simple way of testing the ignition module is to leave the car idling for 30 minutes and then tap the ignition module with a screwdriver.
The clicking noise comes from a part called the starter solenoid. The solenoid connects the battery to the starter motor when the solenoid is energized. The key switch and the safety switches in the starter circuit combine to energize the solenoid. If the solenoid is clicking, the circuit that triggers it is working.
