Several small engines, like those in gas-powered lawn tools, use a recoil starter system. The motor is started from the user, who pulls a rope which spins a pulley which connects to the crank shaft and then the flywheel. Manufacturers like Briggs & Stratton have invented electrical starters that can replace recoil systems. An electric starter uses either an electrical plug or even a battery to charge a motor which spins to turn the crankshaft rather than relying on manpower to pull on a cord.
The Electrical Process
An electric starter is actually a small motor on its own. When you plug it into the wall or battery, it charges also applies current to a solenoid. This engages a lever, which pushes the driveshaft’s drive pinion out. The pinion connects with the starter ring gear on the flywheel. The power in the solenoid compels the engine to spin, which in turn spins the flywheel.
An electric starter can simply be added from this box when the flywheel is compatible. Check your model number to determine whether your machine will utilize an electrical starter. Otherwise, Briggs & Stratton has some starters that include upgrades to the present motor which make it compatible.
