This booklet contains the quick reference and basic troubleshooting information previously found on Tecumseh wall charts and in the Technician's Handbooks. This booklet is designed to be used as a work bench quick reference guide when servicing Tecumseh engines and motion drive systems.
Technician's Note:
Tecumseh engines are manufactured to meet EPA and CARB standards. As a technician, it is unlawful to re-calibrate or replace a fuel nozzle or jet (bowl nut) with a part from any other carburetor that was not originally designed for that engine. All speed adjustments must remain within the limits that are specified for each engine and are not to exceed the maximum. This can only be deviated from if specifically approved by Tecumseh Products, EPA and CARB.
Note: Torque specifications listed should not be confused with the torque value observed on engines which have been run. The Torque specifications take relaxation into account so sufficient clamping force exists after an engine has reached operating temperature.
Torques listed are intended to cover highly critical areas. More extensive torques are found in the respective repair manual.
