How to Identify and Fix Common Gardening Problems ?

Q. Why is my lawn mower turning over but not starting? The most likely reason is bad gas. Gas that sits for many months during the off-season will eventually break down, gumming up the fuel line and carburetor in the engine and preventing it from starting.
An improperly routed belt can cause the engine to die when the blades are engaged. To check belt routing, lower the deck to its lowest setting and remove the belt guard by the drive pulley. Next, lift the belt over the pulley and remove the pins that support the deck at the rear.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

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.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
A lawnmower engine commonly kicks back when the shear key breaks. The shear key commonly breaks because the blade has kit a solid object and come to a sudden stop. Common symptoms of broken shear key include: Engine won`t start.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
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.

Replaced coil an still no fire out of wire kill wire is not hooked up
ANSWER : Hello,
My name is Dane and I am going to help you solve your problem. Ok, there aren’t many things that can cause you a problem here. First, I have to say to check that spark plug. Make sure it’s correctly gapped and not cracked or fouled. Now, check that the flywheel is clean and rustfree. Make sure you have set the coil gap correctly.
To set the gap for the coil, get a regular business card and use it as a feeler gauge. Turn the flywheel so the flywheel magnets are away from the coil. Loosen the bolts to the coil, and pull the coil back, making the gap as large as possible. Rotate the flywheel so the magnets are next to the coil. Slide the business card in between the coil and the flywheel magnets and loosen the coil bolts. If your coil has 2 legs, make sure the business card is under them both. Make sure the coil is even and just snug against the card. Now tighten down your coil bolts and spin the flywheel to remove the business card. Turn the flywheel at least 1 complete turn and make sure it doesn’t contact the coil. You’re done!!! Put it back together and try it again. It’s not unheard of to get a bad new coil. Don’t think just because it’s new it has to be good.Well, I think this should get your problem fixed. Thank you! Dane

My chainsaw has no spark, I have checked the spark plug and it works on another unit, i guess it may be the ignition, ho0wever as it is a small coil I have no way of checking. can the coil be simply tested, otherwise can one be purcahsed.
ANSWER : Yes the coil can be tested. you would need to know the proper specs but with a multimeter you should be able to get a resistance value from your plug wire to ground. With my experience 10000 – 30000 ohms should allow it to run. If this is no help one common thing is your kill switch. A wire should run from the coil to the switch, if this wire is shorted to ground it will not run.

What are the symptoms of a bad coil on my Poulan chainsaw? Mine only sparks at high RPM’s, as tested with my electic drill motor spinning the engine and grounding the removed spark plug to the engine head. I don’t want to buy a new coil if that may not be the problem. I’ve already checked the kill switch wiring and the high tension spark plug wire itself, as well as trying several different plugs.
Thanks! -Rob
ANSWER : There has to be a reasonable spark at hand cranking speed, with most electronic ignitions they work off speed of rotation so you do need to crank the engine at a fair speed, check the air gap between the flywheel magnet and the ignition core, this should be around 0.3mm, if there is not spark at all when cranked well it will be a replacement unit required.

Does not run, will start with starting fluid – Mantis 2-Cycle Tiller
ANSWER : You should never use starting fluid on this model.

Add a couple of ounces of 100% acetone (available at Walmart) to some fresh fuel. Attempt to start for several pulls. Let sit for several minutes and repeat until it sounds like it wants to run.
