Safety According to the American Association of Orthopedic Surgeons' 2006 data, over 100,000 people in the United States suffered an injury in a lawn mower accident for that year. Some of the most common injuries are due to slipping behind and under the lawn mower on wet slippery grass (yikes), or overturning a lawnmower on a steep hill.
Most lawn mower injuries are preventable if some basic safety guidelines are followed. Wear protective clothing such as goggles, gloves, boots and long pants, and never, ever, mow barefoot or in sandals! Have your lawn mower serviced before the start of the season to ensure it's working properly.
Tecumseh Small Engine Repair Near Me
Do not remove any safety devices on the machine! Be sure to add fuel before starting the engine, not when it's running or hot. The liquid could overflow and flame up. Keep hands and feet away from the lawn mower blade even if the machine is turned off. Once cleared of an obstruction, a blade can swing around and cause injury.
Consider Kevlar-filament chaps (when using a chainsaw) that are designed to tangle into the chainsaw chain on contact and stop the saw in a fraction of a second as opposed to cutting into your leg. Don't forget the hearing protection.

Tecumseh Troubleshooting All tests and settings for RPM, Valves, Gov., Leak Down, and Compression are by the book, not “just about right” 1. Try to stabilize engine RPM, by holding steady, the solid link between the gov arm and the carb throttle using your fingers or pliers. If the engine RPM stabilizes the gov or gov adjustment should be checked or reset or sensitivity adjustment changed.
If RPM does not stabilize, check for proper linkage assembly, weak gov spring or bent or worn linkages. Could be worn internal gov parts but this is rare. If 2 Stroke, make sure air vane is not binding, proper assembly or linkages and linkages are not bent. Set RPM to proper setting according to spec. Set by good tachometer. Change RPM up or down 50-100 RPM’s. If variable speed gov - change both idle and top RPM 2.
If constant speed gov – raise and lower within range B. Engine Condition 1.
Fresh Fuel – proper fuel/oil mixture on 2 cycles 2. Warm up Time – 3 to 5 minutes 3. May need to check leak down and compression 4. Proper Valve Clearance – right on not just close. HM80-100 best set intake -.008.009 – exhaust.011.012 5. Check for poor or intermittent spark with inline spark tester 6. If has low oil shut down – unhook and retest 7.
Check shutdown wires and connections for shorting C. Fuel and Carburetion 1. Fresh fuel – proper fuel/oil mixture on 2 cycles 2.
Proper fuel flow to carb - use gravity feed 3. Does using the choke help? Try hand choking if engine has primer 4. Is there outside air leaking into intake system?
Gaskets and sealing surfaces 5. Is intake tube (if used) obstructed? Look inside 6. Proper bowl nut.
Inspect for clean drillings and if has tag material still on drilling. Check idle restrictor jet, damaged, bad drillings and clean. O-rings could be leaking on emulsion tube 9. (Has carb been updated) 10. Lastly, replace carb or bowl kit 2.
Hard or no start a. Fresh fuel – proper fuel/oil mixture for 2 cycles b. Fuel delivery to carb – try gravity feed procedure c. Getting spark. Not just spark, but good spark consistently d. Engine condition (new or old) Leak down and compression.
Compression should be 70 to 100 psi. Below 70 not good. Proper choking and priming. Yes, choking in warm weather in needed. Hand choke carb f. Make sure shut down system in not shorting out. Unhook low oil shut down (when used) and retest h.
Two cycles with primer. Throttle must be opened when priming i. LEV Engine with electric start i. Proper Priming ii.
Check spark during turn over with electric starter iii. If no spark, or poor spark, could be Brazilian coil. (Identified by squared off look and silver manufacturing numbers on it (IE 1A 502) used only during production.
TVT Cold Hard or No Start i. Valve clearance must be.004 on both valves ii. Check proper RPM settings according to specs iii. Are choke plates closing all the way?
Try manual choke with hand or fingers v. Are carbs synchronized correctly – see manual vi. Check compression – Should be 80 – 100 psi. 60-65 psi is not acceptable vii.
Try with low oil shut down disconnected (if used) viii. If no spark – disconnect ground out wires to each coil. (one at a time).
