How to fix a Honda lawn mower that doesn't work
There are pages of engine specifications.
Governors should not need to be adjusted if the arm has been tampered with.If they need to be adjusted, here is how to do it.The engine governor is the most important part of the engine.Your engine's life can be shortened by an improper governor.The engine will destroy itself if the speed is not controlled.Don't run an engine over speed without a load attached to it.It can cause catastrophic failures, like blowing the magneto magnet into 100's of little pieces.Metal coming loose at high speed is something that needs to be taken care of immediately, because it can be a real hazard.This page will show you how to adjust the mechanical governor.Engine runs too fast or too slow are the two main complaints about governors.There is a surge or hunt in the engine.The governor linkage and spring should be inspected before you try to solve them.Make sure the spring is not damaged or stretched.Check the governor static adjustment to see if the free play has been removed.The best way to see how the governor shaft is moving is to move the throttle to full open.Re-tighten the nut if it goes clockwise and turn the shaft all the way clockwise.Make sure the throttle is open after you make the adjustment.Refer to the engine repair manual.After making the above check, restart the engine and see if the governor works correctly.The governor lever should be moved with your finger to open the throttle if the arm isn't working properly.The governor spring can be removed to do this test.You will probably need to check the internal parts of the motor or the static adjustment if it is still over speeds.You can find this at your local repair shop.Governor hunting is one of the problems that occurs.Most of the time, the problem is not the governor, but a partially plugged carburetor, usually a plugged idle circuit or worn linkage.You may have a governor that is set too sensitive if you can rule out the causes and check the adjustments.It reacts too quickly and over compensates for the speed.Many governor arms have holes in them.You can make the governor less sensitive by moving the spring to a hole further away from the shaft.Check the repair manual for your engine to see if it has a way of adjusting sensitivity.You may have to change springs.The "air vane governor" is used by many of the smaller lawnmowers.Similar to a mechanical governor, this system uses the air flowing through the engine to operate a vane against a spring.Air vane governors have a problem with debris in the system blocking air flow.The engine will go over speed when this happens.Keeping the cooling fins clean is important for the proper amount of air to move through the engine.The governor spring is used for an engine that has full air flow.It can over speed the engine if the air flow is blocked.The governor shaft should always be turned in the same direction as the governor arm.The governor arm on the TVS, LEV, TVM, and other similar engines will rock in the counter clockwise direction to close the throttle.To adjust the governor, you need to loosen the screw on the bottom of the arm and push it open.The bottom "clip" is connected to the governor shaft.The governor shaft will be on top of the governor spool.You're done if you tighten the screw.To adjust the governor on a horizontal shaft engine, you would loosen the nut on the arm and push it down.You would tighten the nut when you turned the governor shaft clockwise.
