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 Top 80 website specifies a gap of 0.30mm (0.012″) but new engines from the factory have the gap set to 0.38 mm (0.015″). The bottom line is that the gap could be from 0.30mm – 0.45mm. Too great a coil gap will cause hard starting and slightly retards the spark.
Common armature gap ranges are . 006 – . 010″ and . 010 – .
: an air-filled gap in a magnetic or electric circuit (as the space between the field-magnet poles and the armature in a dynamo or motor) : wind gap.
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.
Spark plug gaps for car engines are typically 0.6 to 1.8 mm (0.024 to 0.071 in). Modern engines (using solid-state ignition systems and electronic fuel injection) typically use larger gaps than older engines that use breaker point distributors and carburetors.
Many think the larger the gap, the better. However, if the gap is too large, and the ignition system can`t provide the voltage needed to spark across the gap, or turbulence in the combustion chamber blows out the spark, misfires will occur.
What should the spark plugs be gapped at? When running a magneto ignition it is not necessary to run a wide spark plug gap due to the longer duration of spark. We recommend that you set your plugs anywhere from 0.018” to 0.025” with the closer gaps being used for higher RPM applications.
To check if the ignition module is getting voltage, set the multimeter to AC voltage (VAC) reading and check for voltage at the thermostat input or 24VAC input to the Ignition Control Module. You should get a reading of 24VAC with respect to common or ground.
The ground or “path of least resistance” for the secondary side of the coil is the gap between the electrodes of the spark plug. If the electricity exiting the secondary can find and easier path to ground through a damaged spark plug wire, boot or grime on the side of the spark plug, it will cause a misfire.
Many think the larger the gap, the better. However, if the gap is too large, and the ignition system can`t provide the voltage needed to spark across the gap, or turbulence in the combustion chamber blows out the spark, misfires will occur.
If the gap is too small, the air can become ionized. When this happens, the air changes from a good insulator, to a good conductor. This is what allows an electrically charged thunderstorm cloud to suddenly release large amounts of current in a lightning strike.
A worn or excessive gap will cause an ignition coil to work overtime, using more voltage to bridge the gap and create a spark inside the cylinder. This increase in voltage stresses the internals of not only the ignition coil but, in certain circumstances, the driver of the ECU.

016″ gap is the most common for those running stock flywheels on Predator 212, 196 Clones, GX200 Hondas, Tillotson 196, 212 & 225 engines small blocks as well as big blocks and v-twins. The stock flywheel magnets are not as strong as those in aftermarket billet flywheels.

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

I have a Lawn Boy 10685 with a Tecumseh motor will it run with rear mulch switch off and either wired together or left open?
ANSWER : If you are getting spark, it should run, usually safety switches connect to ground out the coil to give no spark.
