How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
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.
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.
decompression lever basically used in rope start engine Used in diesel and petrol both . its basic function is to free up cylinder cavity with external environment. So that while cranking it becomes easy to start the engine .
A compression release mechanism works to ease the starting of internal combustion engines by allowing them to spin up to starting speed without having to work against the pumping action of the pistons.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead. If your ignition start or push button start needs replacing, consult a Briggs & Stratton dealer near you.
Loss of performance, rough idling, cylinder misfires, and starting issues are all common symptoms of low compression. Unfortunately, low compression can be caused by a number of engine problems. The majority of the problems relate to the internal engine components like the valves, pistons, and cylinder walls.
The clicking noise comes from a part called the starter solenoid. The solenoid connects the battery to the starter motor when the solenoid is energized. The key switch and the safety switches in the starter circuit combine to energize the solenoid. If the solenoid is clicking, the circuit that triggers it is working.
Too little compression (or too much cam duration) will cause cylinder pressure to drop, which will lower the power output of your engine. Too much compression (or too little cam duration) and cylinder pressure will be too high, causing pre-ignition and detonation.
Any engine, whether gasoline or diesel, requires compression to operate. The process of compression confines and presses a mixture of air and fuel into a small volume within the area of the engine`s cylinder. This process presses together all the molecules under very high pressure.

My Craftsman LT 1000, model No 917272761 will not freewheel. Can you tell me how the control lever works. When I removed the back plate the lever appears to only be attached to the frame via a spring. I do not see any thing else connecting the lever to the transaxle. I assume something has broken off. The manual does not show what the control lever should be attached to. Can you help
ANSWER : You taliking about the relase at the rear you pull out to roll it? it just connects at the top of the transaxel you can go to searsparts.com type in your model# for exploded veiw of the lever ? hope this helps

Engine will stall when levers are moved from park position to center unlock position.
ANSWER : You didn’t mention if the same thing happens engauging the mower deck. If it does both, start with the carb and choke. also, check out the safety switch on the steering handles for a loose wire or a ground short. This should be fairly easy.

How do i replace stud bolts that tighten the bar
ANSWER : If this is the plastic crankcase machine, the bar bolts are pressed into the case, start by removing the muffler, use a punch and drive the broken stud back through the case, it will have a square head on the rear, re fit the new stud, use a spscer and the bar nut to pull the new bolt fully back through.

The engine won’t start
ANSWER : Ensure that the fuel line is not blocked. Disconnect the small rubber hose from the carburetor. Open the fuel on/off lever and see if fuel runs out of the hose, it should. If not, you probably have a blockage in the hoses, the on/off valve is blocked with debris or sludge, or the small bronze filet inside your fuel tank is blocked also. Take fuel tank off to check for blockage of the fitting. Simple process and you only need a 10mm socket.

The rewind spring is broken on my TROY-BILT model 566 mulching mower. The spring is on the underside of the spool (resembles a pulley) that the starter pull cord winds onto. I wasn’t able to find this part in the diagram and parts list of my mower. Anyone know where I can find the spool and spring?
ANSWER : What make is the “engine”, find this out and get back to me.

Need to redo pull starter spring
ANSWER : Normally the spring doesn’t just sprung, it usually breaks. The springs on these engines are bent backwards on both ends so that they catch on to pieces on both the housing and the starter pulley. I would need to see a picture of the unit you have so that I know which screws to tell you to remove. Homeline trimmers are the cheapest on the market and they are very hard to get parts for. Some times if the spring is broken at the ends, we can heat the spring up until it is cherry red and then put a new bend in it and it will work fine. Other times this will not work. Just depends on the unit or where the break in the spring is. If you try and bend the spring with out heating up the metal, you will just break the spring again. So be sure to heat the spring up with a lighter or propane tourch.
