The ignition system on Tecumseh engines can differ greatly based on the model and age of the engine. Older Tecumseh engines use ignition systems that require breaker points, condenser and a separate coil. For proper ignition timing on these systems the points must be clean and properly adjusted. Newer Tecumseh engines use solid state ignition coils which have no breaker points or condenser; however the air gap between the coil and flywheel must still be adjusted to the correct specification.
The first step in diagnosing the ignition system on your Tecumseh engine is to verify spark; however this does not establish correct ignition timing and more advanced testing is required. A common misconception is that solid state ignition coils are less likely to fail. While solid state ignition coils do not have breaker points to foul or condensers to fail, the coil itself can fail and cause improper ignition timing. Refer to the Tecumseh service and repair manuals on our site for more detailed ignition system information.
Common Tecumseh ignition parts found in all systems regardless of age include a spark plug (OEM Champion), spark plug wire, spark plug terminal (with or without a protective boot), flywheel and a flywheel key. Failure of any one of the ignition parts can cause engine malfunction. Refer to our Tecumseh engine parts lookup section to identify your required part numbers.
