In the upper RH rear you will see the new idle adjustment screw, ELIMINATING THE IDLE KNOB OFF THE FRONT as found on the earlier models. But making it necessary to remove the upper cowling to make the idle adjustment. It also eliminates the possibility of enriching the carburetor for a cold start situation. here
The solenoid has 2 circuits, one circuit puts voltage from your battery to the starter motor. These are the 2 large gauge wires attached to the solenoid by the 2 large studs/nuts. One large wire comes FROM the battery to the solenoid, the other large wire leaves the solenoid and goes TO the starter. This we will call the HIGH amperage circuit, because it powers the starter itself. Many times the input wire is red.

Tiller Handle : The tiller handle has been moved to more of a central location instead of off to the left as previous motors. The shift lever is now on the tiller handle at the front of the motor above the mounting clamp screws. There is an adjustment at the base of the shift lever/electric starter button whereby a neutral safety position can be achieved. This is accomplished by the shift lever being positioned so that the starter push button does not engage the starter electric button behind it in the tiller arm if the shift lever is not in neutral. more
On these later motors (1993 +) the exhaust tube is the same for both sizes.
The name Ed Iskenderian is a legend among racers worldwide. Ed's life history parallels the proverbial success story. He was born in 1921 in the grapevine country of Tulare County, California. His future as a winemaker never materialized because several heavy frosts destroyed the vineyards. These conditions forced the Iskenderian family to move to Los Angeles. here
While attending Polytechnic High School in Los Angeles, Ed's pet project was building a Model T Ford roadster. Ed learned the fundamentals of mechanics by working with the Model T Fords and later adapted the overhead conversion by Frontenac (more commonly known as Fronty), as well as the George Riley head known to the racers in those days as the "multi-flathead."

First The governor shaft should always be turned in the same direction the governor arm turns to open the throttle wide open. For example, on Tecumseh TVS, LEV, TVM, TVXL and other similar engines, the governor arm rocks in the counter clockwise direction to close the throttle to idle. To adjust the governor, you would loosen the screw on the bottom of the governor arm and push the governor arm so the throttle is wide open. Then you would turn the bottom "clip" (which is connected to the governor shaft) counter clockwise. This will set the governor shaft on top of the governor spool. Tighten the screw and you're done.
Many of the smaller lawnmowers used what is called an "air vane governor". This type of system uses the air flowing through the engine to operate a vane back and forth against a spring, just like the mechanical governor does. The big problem with air vane governors is debris sometimes collects in the system blocking air flow. When this happens the engine will over speed. So, with an air vane system it is very important to keep the cooling fins clean so the proper amount of air can move through the engine. The governor spring is precisely calibrated for an engine that has full air flow going through it. If the air flow is blocked it can over speed the engine.
One of the most important parts of your engine is the engine governor. An improperly adjusted governor can shorten your engine's life. If engine speed is not controlled, the engine will destroy itself. Never run an engine over speed, especially without a load attached to it. Even for a short period of time it can cause catastrophic failures, like blowing the magneto magnet into 100's of little pieces. Over speeding is something that needs to be taken care of immediately, because it can be a real hazard with metal coming loose at high speed. This page will explain how to adjust the mechanical governor on Briggs and Stratton and Tecumseh Engines.
After you have made the above check, restart the engine and see if the governor now operates correctly. With the engine at idle, move the governor lever with your finger to open the throttle and it should push the arm back toward idle if working properly. One way to do this test is with the governor spring removed. If it still over speeds or has no push toward idle, you probably will need to have the internal parts checked inside the motor or recheck the static adjustment. See your local repair shop for this!

Generally Governors should never need to be adjusted, unless the governor arm has been removed or tampered with. In the event that they do need adjusted, here is how to do it.
The other problem that often occurs is governor hunting or surging up and down. Most of the time this is not the problem of the governor, but a partially plugged carburetor, usually a plugged idle circuit or worn linkage. If you can rule out these causes and have checked the adjustments I talked about above, then you may have a governor that is set too sensitive. In other words it reacts too quickly and over compensates for the speed. Many governor arms have several holes in the arm to change sensitivity. By moving the governor spring to a hole further away from the governor shaft you will make it less sensitive. Before playing with this, check the repair manual for the engine you have and see if it has a way of adjusting sensitivity. Sometimes you may have to change governor springs, etc. [links]
