This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.

This exhaust gasket is a genuine Midwest Engine replacement part for appliances that use small engines, such as chipper shredders, snowblowers, leaf blowers, and lawn mowers. The function of an exhaust gasket is to seal off the carburetor from the exhaust tube in order to protect the engine from the accumulation of dirt, debris, and gunk within the inner workings. The exhaust gasket may require replacement over time from general wear and tear. If the exhaust gasket is not sealing, allowing dirt and debris to accumulate within the carburetor and leaving the exhaust tube exposed, the part should be replaced immediately. Evidence of a damaged exhaust gasket could also manifest in the form of oil leakage, black smoke arising out of the exhaust tube, and unusually low pressure from the combustion when using the appliance. Any of these symptoms can be attributable to multiple factors, so one should assess if the exhaust gasket is responsible before ordering a replacement.This exhaust gasket is compatible with the following brands: Briggs and Stratton, Cub Cadet, Toro, and Simplicity. This part sold individually.

This genuine Midwest Engine foam pre-cleaner can be used as a replacement part for appliances operated by small engines, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. A foam pre-cleaner is an air filtration system made of a foam layer through which the air must pass before accessing the primary air filter. The purpose of a foam pre-cleaner is to put less stress and strain on the primary air filter, thereby requiring fewer primary air filter changes. The foam pre-cleaner in a small engine appliance should be cleaned once every 24 hours of appliance usage; if it is not cleaned regularly on this timetable, it is highly likely that it will have to be replaced after less than optimum hours of appliance usage. If the regular air filter has to be changed more than usual, it is likely that the current foam pre-cleaner has to be replaced as well. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This foam pre-cleaner is compatible with the following brands: Midwest Engine, Briggs & Stratton, Toro, and Simplicity.

This is a foam pre-filter that is used to help prevent dust, pollen, and other debris from clogging the air filters of small engines. One of the most common problems faced by small engines is an inadequate air supply caused by air filters that have become mired with airborne debris. Cleaning or replacing filters can become a tiresome and expensive proposition. If filters are not adequately cared for, they perform poorly, waste gasoline, pollute the air, and cause internal engine damage. A good way to help an air filter do its job is by adding a foam pre-filter in the air filter compartment. Pre-filters are exposed to all the things that clog air intakes, so periodically, they also must be replaced. Foam pre-filters are designed to fit snugly inside the housing of the air filter of virtually all small engine housings. To install a pre-filter, remove the air filter housing by taking off the one screw holding it in place. Remove the air filter from the housing and place the pre-filter inside against the exterior wall of the housing with the arrows pointing up. Reinstall the air filter. The paper of the filter should fit perfectly against the labeled side of the pre-filter. Now simply reattach the air filter housing. Genuine Midwest Engine makes this OEM replacement part, and it is sold separately.
