How do you fix a pull start that won't retract?
If the rope does not recoil, the spring needs to be recoiled manually or replaced, depending on the problem with the spring. Remove the starter from the engine. Inspect the recoil spring. If the spring is broken it will need to be replaced; if not, the spring can be recoiled.
If you feel significant resistance when pulling the starter cord, start by checking the automatic brake. If this lever isn't at fault, grass and other debris may be preventing the blade, which is connected to the starter coil, from turning.
In the center of the pulley, a recoil spring connects to the pulley through a hook. When the starter rope gets pulled off the pulley and out of the engine, the recoil spring stretches out. This allows the operator to continuously pull the rope to get the engine moving faster and faster toward combustion.
One way the starter cord can get stuck is due to hydraulic lock, which is caused by oil getting trapped in the combustion chamber. You'll need to release the compression and the oil, so remove the spark plug and then give the cord a tug.
If it's full of oil, the piston cylinder may be full of oil, causing hydro-lock. This can happen when you tilt the mower forward and hold it that way for a few minutes. But when the cylinder is full of oil, the piston has to work against the oil and can lock.
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.
For ignition coils (and many types of electrical transformer), the secondary winding is made with more windings than the primary winding. When a spark is required at a spark plug, the ignition system will switch off the current flow to the primary winding, which will cause the magnetic field to collapse.
