Tobin Injury Law advises Lake Tahoe and South Lake Tahoe residents to regularly degrease their small engines, which will help prevent debris build-up in your engine and extend its lifespan.
Spray the degreasing agent liberally onto greasy and dirt-encrusted areas in a well-ventilated space, then allow it to sit for 15 minutes before wiping it away with a clean cloth.

Disassemble the Engine
Once your equipment is located in a well-ventilated environment, use a degreasing agent like Briggs & Stratton Heavy-Duty Degreaser (p/n 100044) liberally on surfaces covered with grease or dirt build-up to degrease them. Give this process time to work before wiping away residue with a cloth.
Explain the workings of a four stroke gas powered engine by disassembling, inspecting, servicing, and reassembling it using appropriate tools and procedures. Use concise steps and detailed notes when disassembling an engine in order to reinforce lecture-based theoretical discussions as well as utilize manuals with specifications in them.
Demonstrate proficiency in precision measuring skills. Conduct an initial inspection on all components to be cleaned prior to cleaning them, including: * Water pump replacement * engine radiator removal * removal and installation of air hose and filter * removal, disassembly and cleaning of carburetor (adjusting mixture screws ; clean, remove and replacing bowl and valves). ( Inspect, measure and replace exhaust system components * inspection disassembling hydraulic or mechanical lifters (disassemble head to remove ridge from cylinder wall ) * disassemble hydraulic/mechanical lifters * disassemble head to remove ridge from cylinder wall before cleaning * demonstrated camshaft resurfacing techniques
Attain and prepare power tool equipment for work; drain fuel into a red container marked “Waste Fuel” before emptying tank; use wooden blocks to support engine in vise for clamping without damage, then demonstrate proper ways of supporting and clamping engine parts during disassembling process in vise.
Clean the Carburetor
Carburetors play an essential part in keeping small engines running efficiently. Over time, gas will dry out and form sticky deposits that clog air and fuel passages within the carburetor if left untreated, leading to decreased performance from both fuel and spark plugs.
Keep your carburetor running at peak condition with regular use of carb cleaner, available in spray cans. Apply it directly onto the carburetor to remove deposits. A good cleaner may even prevent further issues with rust or corrosion from developing on its surfaces.
When using a carburetor cleaner, always ensure to wear durable gloves to protect your skin and work in an area with adequate ventilation so as to avoid breathing any serious fumes. Before beginning cleaning your small engine, ensure all its components have been turned off first and spray carburetor cleaner on its surfaces and surrounding components of the small engine – after about 10 minutes have passed since application, use brass brushes on metal components of the carburetor and nylon ones on plastic components while making sure to thoroughly scrub its vents as well.
As part of your carburetor cleaner regimen, it is also advisable to spritz gas ports, float and needle ports, air/fuel port, throttle plate choke plate jet and jet. A wire should then be used to thoroughly clear any portholes which have become blocked up with debris.
If your small engine seems to have any issues after this test, drain and disassemble its carburetor for more thorough cleaning. If this takes too much time or you don’t have one handy, try spraying some carburetor cleaner into its carburetor while it runs to see if that helps.
Once the carburetor has been thoroughly cleaned, it should be rinsed with water to remove all traces of cleaning solution. Before reassembling it, allow it to fully dry before testing its functionality by attaching it back to your engine and making sure both throttle and choke plates can move freely.
Clean the Spark Plugs
An engine with dirty spark plugs consumes more fuel than necessary and leads to other issues, including misfiring, power loss and misfires. One effective solution for preventing such issues is keeping them clean by using basic supplies readily available at most hardware stores – like spark plug socket wrenches, brake cleaners and WD-40.
Before beginning the cleaning process, ensure the spark plug is cold to touch. Remove its black wire and brush away any debris in its immediate area before applying a generous amount of rubbing alcohol to its tip and applying additional amounts as necessary to break up grease and dirt build-up. After cleaning it with an old toothbrush or scrubber pad, clean its metal surface and ceramic insulator using a clean rag to finish up.
Use a wire brush to scrub the threads of your spark plug with oil and dirt that has built up, making installation simpler when finished. Make sure you wear gloves for this step to protect against accidental stabbings to your fingers.
Make sure that the spark plug electrodes are smooth using 220-grit sandpaper; this will remove discolored build-up and reveal bare metal surfaces. When complete, you should be able to see your spark plug gap clearly; otherwise keep sanding until this occurs.
Spark plug gaps play a pivotal role in the performance of any small engine, so always follow manufacturer recommendations when setting them.
Once your spark plug has been properly cleaned and restored to working condition, its performance should be tested by exposing it to flame. After holding it until it glows red-hot for some time, allow it to cool on a nonflammable surface before installing back in your engine. Upon installation make sure it’s properly adjusted using a gap measuring tool; otherwise it could fail to generate spark during engine operation and lead to ineffective lawnmowers that waste fuel while producing less power than intended.
Clean the Air Filter
Air filter maintenance is key to engine performance. An engine requires clean air for maximum fuel efficiency and an optimal gas/air mix, and filters that have been properly maintained help achieve an even burn that reduces engine wear and tear. One way of determining whether an air filter needs replacing or cleaning is by looking at its condition: If its pleats have become heavily clogged or discolored it should likely be considered worn out and need replacing as soon as possible.
Filters should be regularly washed with hot water and detergent designed to cut grease before being rinsed and wrung out. After being thoroughly washed and rinsed, foam filters may benefit from having some motor oil added afterward; though use caution as too much may damage your exhaust system.
If you own a paper filter, stuff a shop rag into its center to prevent dirt from flying back out when using an air compressor to clean it. Carefully remove this layer before blasting all areas with spray nozzle. Gently tap filter against hard surface to loosen any remaining dirt before setting aside somewhere warm until drying complete.
Before running your small engine, always ensure it’s in a well-ventilated area and the spark plug wire has been detached from its spark plug. Gasoline has a limited shelf life and may deteriorate over time – leading to rough idling, varnish deposits and reduced combustibility. A few drops of fuel stabilizer can extend its usability but if sitting idle for over four months recycle and purchase fresh containers of gasoline.
