Spark Plug - Part # 1605018 Mfg Part # 71G

Spark Plug

RepairClinic Item # 1605018 Aftermarket (Non-OEM) part

If the small engine is hard to start the spark plug might be defective. All small engines have an ignition coil. The coil is the device that provides spark for the spark plug(s). If the coil is bad power won't get to the spark plug(s). The coil is essentially a small, induction generator. It is mounted next to the flywheel. The flywheel has one or more strong, embedded magnets. As the flywheel spins, the magnet(s) zip past the induction coil, this action of a magnet passing past a coil induces a voltage. Depending on the design of the coil and the strength of the magnets, a stronger or weaker spark can be created and delivered to the spark plug(s). Each time the flywheel spins around a spark is generated. The best way to test a spark plug is to use a spark plug tester. The spark plug should have a strong, visible spark between the electrodes when the engine is cranking. If it doesn't, replace it.

Carburetor - Part # 1567994 Mfg Part # 794572

Carburetor

RepairClinic Item # 1567994

If the small engine is hard to start it might be getting too much fuel or not enough fuel. In either case start with the carburetor. If the carburetor is clogged with varnish deposits from old fuel, or if the choke isn't closing properly the small engine is hard to start. Try draining all of the old fuel from the carburetor and gas tank. Use fresh fuel with a stabilizer. If that isn't effective it may be easier to replace the whole carburetor.
