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 :

The spark plug gap on your Insight or Insight Gold Mower is . 030 or (. 076mm).
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.
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.
The gap setting is different for each vehicle but most are somewhere between 0.028″ and . 060″. Consult the owner`s manual or Champion ® catalog to find the recommended setting for the vehicle you`re working on.
The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear. It is always best to check the gap against the manufacturer`s specifications.
However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn`t run at all.
Simply change the filter to give your mower more thrust. Finding the air filter should be easy as it is located on the left side of the mower`s engine. You can have it cleaned or you can opt to buy a new one. Treat your lawn mower`s engine the same way you treat you car`s engine.
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.

Changing the Spark Plug and Air Filter are good ideas, and are general maintenance items. The carb cleaner could also be sprayed into the carb through the intake. If those items dont restore power, there is a good chance your motor`s compression is low – and you need to rebuild it.
A: This spark plug should have a gap set to 0.02 inches.
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench. (Taper seat: About 1/16 turn more.)
A: This spark plug should have a gap set to 0.02 inches.
