Experienced gardeners share their insights in answering this question :
Take air cleaner off. Shoot some spray carburetor cleaner in the carburetor and try to start Try this a few times to see if the engine will fire.. If it fires or starts then there is a fuel delivery problem. Could be a dirty fuel filter, bad (stale) gas, a dirty carburetor. If it does not start with the carb cleaner, check the spark plug. It may be fouled. Check for spark – take plug out of head. with the plug attached to plug wire, hold plug with a pair of insulated pliers, and touch outside of plug where the threads are to the engine, while some one pulls on the start cord. You should get a bluish spark. If you get a weak spark use a new plug and try again. There should be a bluish spark. Make sure you hold the plug against the engine making good contact. If no spark at all, could a bad magneto.

Getting back to the carburetor. If you think the gas in the tank is stale, drain it out and put fresh gas in the tank. Change the gas filter.
The arburator may be cleaned by pouring a 1/2 can of fuel system cleaner in the gas tank and spraying the spray cleaner down the carburetor throat.

Your Mower Won`t Start:

Other possible causes include: 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.

Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
The most common signs of bad spark plugs include start-up trouble, rough idling, sluggish acceleration, declining fuel economy, engine misfiring, and engine knocking.

Craftsman 6.75 self-propelled…This is for a friend of mine. She has a broken arm and her mower will not operate as it should. The self-propelled function is not working. She spoke with someone who suggested that a cable may need to be tightened. The problem is, she sees two cables and isn’t sure which one needs tightening. I’m away from home, and unable to physically help her. This seems to be the only problem with the mower. Any help you can give is appreciated.
Rob
ANSWER : The self propel lever is the bottom one, the top one is the running lever. Have her check the cable coming out of that one.
