Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Powered by a Briggs and Stratton 148cc SQ Series 450 4-stroke engine.
If your Briggs & Stratton engine has a spark but won`t run, then it is most likely a problem with the gas or air intake in the engine. The spark on the spark plug ignites the gas in the piston, but if the air filter is clogged or the gas can`t flow, then the engine won`t start.
Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to run roughly. If the carburetor is clogged, try cleaning it with carburetor cleaner.
Use a spark plug socket to remove the plug to get a good look at it. The damage you see will help you determine the cause of the misfire. If the spark plug is just old, replacing it may solve the problem. Make sure to replace and properly gap new spark plugs.

Stale fuel, dirt, and debris are the most common cause of outdoor power equipment not starting or running properly. If you store equipment with untreated gas in the tank, it can lead to engine damage.
Check the following: Clogged muffler, clogged exhaust port, fuel restrictions, low compression, poor ignition spark, too much oil in gas or improper air/fuel mixture in carburetor. . Clean carburetor jets and air filter. Check clutch gear wheel for worn or greasy clutch pads.
You can either clean the air filters, or you can replace them with new ones. If you have a foam filter, you can clean it with a drop of dish soap and warm water. Remember to air-dry them before using them again. But if you have paper air filters, you must replace them during the maintenance of your mower.
The mower surges when the carburetor sucks air through an unsealed gap in the air intake manifold instead of through the air filter. Dirty carburetor. Clogged fuel jets inside the carburetor commonly cause the lawn mower engine to surge. Clogged jets can`t provide the right mix of air and fuel to the engine.
A spark plug that is damaged, worn, or has an improperly set gap between its electrodes creates a weak spark. As a result, the fuel may not ignite in the cylinder, but it might ignite when it reaches the hot exhaust muffler. The result is a loud backfire. Poor spark also results in a mower that runs unreliably.

There are plenty of free or cheap lawn mowers out there, trust me.

Chain oiler. turn up? – Husqvarna 450 e-series 18" Chain Saw
ANSWER : Release the chain brake and remove the bar and chain. Clean the engine side case where the bar fits to, then start the engine and observe whether oil oozes out of the port. If ok, clean the small oil passages in the drive end of the bar–they run from the large holes out to the chain groove an each edge. Check the oiling by running the saw tip at speed near some cardboard–it should throw off a thin line of oil. Look for an adjustment screw head set into the rear-underside of the case near the chain return area. Turn CW to decrease oil volume. Hope this helps!
