Kohler Twin Cylinder Electrical And Governor Setup

Electric System Installation and Troubleshooting

Overview of Electric System Setup

• The speaker discusses the temporary installation of the electric system, highlighting the need to remove coils for flywheel installation and clean up wiring that was improperly connected to the intake manifold.

• A demonstration of wiring is provided for those rebuilding similar engines, emphasizing the importance of understanding connections to avoid issues.

• The stator is tested and found shorted; it requires replacement. Key points include checking resistance with a voltmeter and identifying damaged regulator pins.

Wiring Connections Explained

• Detailed explanation of wire connections from an electric box: yellow and brown wires connect to coils, green wire connects to engine frame, while white wire links directly to harness.

• Instructions on connecting harness wires: green connects to oil pressure sensor, brown connects to regulator's middle terminal. Emphasis on installing stator before flywheel.

Adjusting Linkages and Governor

• The red wire from the electric box connects to carburetor solenoid; testing coils involves removing wires and using a multimeter set on ohms.

• Discussion about missing plastic bushing in linkage; a replacement part was sourced cheaply online. Instructions are given for disconnecting and reinstalling linkages properly.

Carburetor Installation Tips

• Recommendations include installing choke before carburetor for easier access during setup. Importance of ensuring all connections are secure before adjusting governor linkage is stressed.

• Explanation of throttle linkage adjustment process, including ensuring proper positioning of carburetor components during adjustments.

Final Steps in Stator Replacement

• Ensuring that the baffle at the bottom of the carburetor is fully open during adjustments; specific techniques for holding components in place while making adjustments are described.

• After receiving a new stator, tests confirm its functionality through resistance checks. Preparation steps for flywheel installation are outlined, including setting clearance between coils and magnets correctly.

How to Properly Set Up Engine Components

Importance of Correct Setup

• When adjusting engine components, if a filler gauge is unavailable, thick paper can be used as an alternative to ensure proper spacing between the magnet and coil. The ideal gap should be about 10 thousandths of an inch.

• Incorrectly setting the magnetic distance can lead to severe engine damage. If the magnet is too close to the center of the flywheel compared to another magnet, it may collide during rotation.

• It’s crucial to double-check that all settings are accurate before proceeding with further assembly or adjustments, as this could prevent potential mechanical failures.

• The speaker emphasizes having significant compression in the engine, which indicates that proper setup is essential for optimal performance and safety.

• Careful attention must be paid during installation; any oversight could result in catastrophic damage not only to the engine but also potentially affect other connected systems.
