High torque at high efficiencies, minimal loss of speed as motor is loaded.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Technically Speaking INTEGRAL COMMUTATOR TECHNOLOGY The armature rotor uses solid copper conductors known as buss bars rather than the conventional copper wire windings. These buss bars have very low resistance, resulting in less heat build up and higher energy efficiency in the rotor. COPPER BUSS BARS The buss bars are stamped, formed and coated before assembly on the rotor.

For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 New Products The Briggs & Stratton Engine Minder is designed to prompt consumers to perform recommended maintenance on their Briggs & Stratton engine. How It Works The primary side of the engine magneto powers the Engine Minder's microprocessor; a 12V battery is not required. When the engine has run for 50 hours, the Change Oil" symbol will flash" indicating that recommended maintenance is required.

Use a grinder to shape one end of the cutter and remove sharp edges, then just hook the tool behind the seal and rock it. Caution: Care should be taken so that the tip of the tool does not damage the seal bore.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Service Tips & Tools Brent Allen, a Master Service Technician from George West, Texas suggests purchasing a pocket otoscope to enhance visibility of carburetor circuits. This idea provides another way for technicians to see deep inside non-removable carburetor passageways.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Service Tips & Tools Aaron Gray, a Master Service Technician and a Master Parts Pro from Columbus, OH came up with the following idea for checking an engine for leaky gaskets or porosity. Drain the oil and install a modified oil fill cap. Attach the 19493 Mity Vac Pressure/Vacuum Pump to the fill cap and while pinching off the breather tube apply pressure with the pump.

For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 A Closer Look A CLOSER LOOK – FOURCEt ENGINE The Fource engine uses a spring loaded rocker switch and a maintenance free electronic ignition module. The connecting rod is a stamped aluminum one-piece assembly using needle bearings at both the piston pin and rod journal. Piston is a cast, nickel plated, symmetrical style with three rings. Crankshaft is an open, cantilever type, supported by two main ball bearings.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 A Closer Look The valves are both stainless steel and use a 45 degree angled valve face. Valve clearances are established by setting the piston ¼" past top dead center on the power stroke. Trimmer engines are typically multi positional which can be a challenge for a 4 cycle engine. There is no mixing of oil and gas which allows the engine to burn cleaner and more efficiently, unlike 2-cycle engines.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 A Closer Look Both the cylinder head and flywheel are cast aluminum and are produced exclusively for Briggs & Stratton. The flywheel incorporates a cast in key for timing. The carburetor is a Walbro style with a fuel pump combined system. The green hose is color coded to provide easy identification as the fuel supply and the clear hose is for the fuel return back to the tank.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting GOVERNORS: THEORY, ADJUSTMENT AND TROUBLESHOOTING Engine governor systems have been around almost as long as engines. Before governors were added as a separate system, speed was controlled by the work the engine was required to do. These primitive systems used carburetors without throttle plates or with throttle plates held in a fixed position.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Variable speeds require some method to increase and decrease spring tension incrementally and the aptly named speed control bracket is typically used. Operation is fairly straightforward. As the flywheel turns, the vanes capture air and move it in the direction of flywheel rotation.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting MECHANICAL GOVERNOR The mechanical governor system functions on the same principles as the air vane system. A governor spring is still used as one half of the balance" equation, acting directly on the throttle plate. An engine driven governor gear assembly (not shown) creates the second force.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting CHANGES IN LOAD When a load is applied, engine speed is reduced and the flyweights move in, reducing the force. The governor spring gains the advantage and pulls the throttle plate open. Engine speed increases and the flyweights move out, balancing the forces again.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Throttle plate closed Throttle plate open To establish which direction to turn the governor shaft, refer to the appropriate repair manual or perform the following procedure. Manually turn the throttle shaft so that the throttle plate is in the closed position or that the throttle shaft is against the idle stop screw if so equipped.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting The use of an electronic governor is fairly limited on Briggs & Stratton engines, being fitted on several V-Twin Vanguard engines and on a few three cylinder liquid cooled gas powered engines. The electronic governor system offers some distinct advantages but does have some limits. At this time, only two top no load speed settings are available and aimed at the generator market.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting GOVERNED IDLE Briggs & Stratton air cooled engines are arguably at their best when run at top no load speeds. The cooling, lubrication and governor systems are all at their peak. Few would consider pushing a lawn mower into the grass with the engine at idle speeds. There are, however, some applications where loads applied at idle or slower throttle speeds are convenient for consumers.

For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Follow this procedure to determine if an overspeed governor problem is internal or external: Perform a static governor adjustment. Remove or unhook governor spring(s). Start engine. Quickly move throttle shaft towards the wide open throttle position. If the internal governor gear assembly is functioning, the throttle shaft should immediately return to idle. Problem will be external.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Hunting and surging These are undesirable operational traits that may be attributable to the governor system. Hunting is a quick changing of rpm when set at a given speed. Surging is a slow, cyclical change of rpm, also when set at a given speed. Since both have similar causes, they are generally considered together.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Inability to handle load This may be a tricky area to investigate, as a variety of areas may have to be explored. Although it is usually OK to assume that an OEM piece of equipment with the original engine should be capable of performing its job, this is not always the case. For the purpose of this discussion, we will assume that the engine and equipment are properly matched.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting SPECIAL CIRCUMSTANCES Dual governor springs on walk-behind mower engines. Several years ago, a second governor spring was added to some 9 and 10 cubic inch displacement vertical shaft engines. This may appear to be a governed idle spring and may even be listed as such in some illustrated parts lists.
For Briggs & Stratton Discount Parts Call 606-678-9623 or 606-561-4983 Governors: Theory, Adjustment and Troubleshooting Generator engines – fooling governor system by overspeeding Most engines for generator application are set at speeds higher than the rpm required for the proper frequency to allow for governor droop rpm loss. Normal, loaded operating speed for 50 hertz generator sets is 3000 rpm and 60 hertz is 3600.
