If an 18.5 Briggs and Stratton engine is not spinning fast enough to start, it could be due to a weak battery, bad connections, or a faulty starter. Check the battery voltage and ensure all connections are clean and secure. Additionally, inspect the starter and solenoid for any signs of damage or failure. If these components are functioning properly, the issue may lie within the engine itself, such as compression problems or fuel delivery issues.
I have a 14.5 Briggs and Stratton engine on a Ranch King riding mower that will not start. After spraying starter fluid into the head, and air cleaner it fires for a second, but will not run. It is getting gas.....coil??? or something else?
Briggs has a rudimentary wiring diagram for the operation of an electric start engine. see the link below.
It is the whole assembly containing the pull start (if applicable) or the metal or plastic shroud surrounding the flywheel (it spins when you start the engine ).
Clean out the carburetor with gas, the reason it wont keep running is its not getting enough gas through the carburetor.
Try 32 thousands, to start, depends on how much compression the engine has at this point.
Yes, a 5.5 Briggs & Stratton engine can be converted from a pull start to an electric start, but it generally requires specific components. You will need an electric starter motor, a compatible flywheel with a ring gear, a battery, and a wiring harness to connect everything. It's important to check the engine model for compatibility with the electric start kit and follow manufacturer instructions for installation.
bad gas, dirty carb needs new sparkplug. youtube has repair vids on how to do what. user (davidsfarm) has great tips
dirty fuel filter or water in the bowl of the carb
Might be in your ignition : lose wire, bad switch : when it won't start check for spark .
Because its a pos I have a brand new one that won't start.
To rebuild a Briggs and Stratton OHV engine, start by disassembling the engine carefully, noting the order and orientation of parts. Clean all components and inspect them for wear or damage, replacing any faulty parts such as gaskets, rings, or valves. Reassemble the engine using a torque wrench to ensure proper tightness of bolts, and follow the manufacturer's specifications for reassembly. Finally, perform a thorough check of the fuel and lubrication systems before starting the engine to ensure it runs smoothly.
