Why do my lawnmower wheels wobble?

As lawnmowers get used, eventually the hard plastic housing on the wheel hub will wear against the axle bolt and start to “wobble”. A quick fix for this is to install a bushing into the wheel. This is done by removing the “wobbly” wheel form the mower and drilling out the axle bolt hole in the wheel from a wobbly 1/2″ to a new 5/8″ ID (inside diameter) hole. Then purchase a nylon bushing with a 1/2″ ID and a 5/8″ inches OD (outside diameter) and tap this bushing into your newly enlarged axle hole.

The nylon material of the new bushing will give the wheel new strength and longer life.

What is tire ply? Should I use “2 ply” tires or “4 ply” tires? What’s the difference?

Ply rating, in regard to small power product tires, is the number of nylon, polyester or even steel cord layers that are embedded under the rubber tread of a tire. You can’t see these various ply layers but they are important to ensure that the tire can handle its published rating. The number and type of ply plays a major role in the performance and load carrying capacity of a tire. There are differences between tires with different number of ply. A 4 Ply tire is more resistant to punctures, can take more load, and take tire repair better than a 2 ply. A 2 ply tire is usually less expensive than a 4 ply, can’t take as much load as a higher ply tire and tends to flex more when hot.

When shopping for replacement tires for your small power product it is always best to acquire the exact tire that is recommended by the manufacturer. It is not advisable to replace a tire with a lesser ply tire.

HOT TIP! Do a better job sharpening your chain saw chain with…..

OK Ready for it…Wear magnifying glasses!

Yup sharpening your saw chain wearing magnifying glasses will produce a much improved finished product.  I have them for fishing, polarized with small magnifying lenses built in for tying line. I was using them to put an edge on my knife and noticed quite a difference. These glasses are inexpensive ( $30 – $50) and come in various magnification. Some even come with LED lights in the eye glass arms which sure comes in handy in dark places.


How to clean carburetors without harsh chemicals? Build a “Soda Blaster”!

That’s right make a soda blaster and blast the grease and grime off your parts. We all know that the chemical cleaners are not what they once were and most still use harsh chemicals that you can’t rinse down the sink.  A Soda Blaster is basically a sand blaster using BAKING SODA – completely safe and harmless and cheap! We all likely have some baking soda in our kitchen cupboards already!

The Soda Blaster uses a simple venturi tube (piece of plastic tubing) on the end of your compressor air gun the other in the box of baking soda. The Low pressure created in the venturi draws the baking soda up the tube where the high pressure air fires it at the target – safely blasting away the grime. Any residual baking soda is simply rinsed away as it is dissolves in water.

The following link has a great step by step guide to making a Soda Blaster, check it out.


As with any device that uses compressed air – proper safety protection should always be worn.

Installing 10 mm Spark Plugs – be careful!

How tight you install any spark plug into an engine head is critical. Small engine spark plugs come in different sizes with the most common being 14 mm, 12 mm, and now even 10 mm.

Many newer lawn and garden engines now take the tiny 10 mm spark plugs. The body wall thickness of these spark plugs are deceptively narrow. Once installed these spark plugs have to come back out eventually and over tightening them can cause them to snap off at the threads because a spark plug, like any bolt, requires more torque to remove than to install.

Plug manufacturers have preached for years about using a torque wrench when installing these 10 mm plugs and for good reason. Removing a broken over tightened spark plug can be a big expense. You shouldn’t rely on just the “feel” of tightness – either use a torque wrench or a “seated rotation” guideline to ensure the proper tightness of any small engine spark plug that you install.


Are there any ”environmentally friendly” chain saw oils?

For sure! And a great choice for Mother Nature!

Bio-degradable saw chain and bar oil is formulated to be nontoxic, clean, renewable and even considered by some – a better overall lubricant then the petroleum based product. We all know that chain oil is a critical part of any chain saws effective and safe operation. Unfortunately, the method of applying this lubricant on a chain saw is considered a “total loss lubricating system” process. This means that all of the lubricant ends up in the environment – either sprayed all over the work area or mixed in with the saw dust. Not a nice way to treat Mother Nature!

Bio-degradable oils like Laser TerraSafe Oil is a high quality biodegradable bar and chain saw lubricant formulated with the best optimized biotechnology using USA-grown natural seed oil that is specifically engineered and recommended for use in all types of chain saws. This oil replaces and mixes freely with petroleum-based bar and chain oils and is suitable in both automatic and manual lubrication applications.

Bio-degradable oils are a superior choice for chain saw lubrication with good lubricity, a high flash point, non-irritating to the skin, but best of all – 100% biodegradable. In fact, Bio-oils are often required when cutting on government land because it is aquatically non-toxic as well!





Bio-degradable oils – good for your saw – great for the environment!


Do I need to “break in” my lawnmower Electric Clutch?


Electric Clutch


Yes, you should “break in” an electric clutch!

A new clutch on your riding mower should be run through a break in process or what is commonly called BURNISHING. This process helps to prepare the clutch surfaces and hence will help to extend the life of the electric clutch. It’s quite a simple process and will only take a few minutes to perform.

  1. Start your mower with clutch disengaged, increase throttle to about 50%
  2. Engage clutch for 10 seconds then disengage clutch
  3. Repeat this five times
  4. Now increase throttle to approximately 75%
  5. Engage and disengage your clutch for an additional 5 times
  6. Check the blade and clutch bolt torque and you are ready to start cutting

Electric clutches aren’t cheap so it is well worth the few minutes of effort to help extend the life of your new electric clutch.

What is the difference between an ” A ” belt and a ” V ” belt?

An “A” style belt are typically industrial belts that are measured for size on the inside of the belt whereas “L” style belts are measured on the outside.

The size difference between an ” A ” belt and a ” L ” belt is always 2 inches.

Therefore, if you have an “A-40″ belt and you wish to replace it with a ” L ” belt you will need a “4L420″ to replace it.

Similarily “B” style belts are measured for size on the inside of the belt as well  – however there is difference of 3 inches to a ” L ” belt

So, if you have a B-56 belt that you want to replace with a ” L ” belt you will need a 5L590 belt to fit properly.

Kevlar V belts are traditionally used with outdoor power equipment, these are coded  as 4L,5L The Kevlar is critical when drives need reverse bending such as on idlers.





How do I sharpen chainsaw chain with an electric sharpener so that the left and right cutters are equal?

Uneven sharpening of left and right cutters with an electric sharpener is a common problem that is easily resolved with this little tip. To ensure even cutter sharpening it is imperative that the center of the electric sharpening stone is lined up with the center of the vise.








I simply use a round chain saw file clamped perpendicular in the vice so that I can easily see how the vice aligns to the centre of the sharpening stone. The file should be centered equally on the sharpening stone retaining bolt.














If the file does not line up with the center of the sharpening stone, use the adjustment screw on the vice (see arrow in picture) to adjust the alignment so that it does.







With your sharpening stone now centered to your vice both your left and right cutters will sharpen the same! I hope this helps and don’t forget to tilt the vice 10% for those chisel cutters!


Why does my trimmer line keep breaking so easily?

Trimmer Line Breaking? Soak it in water! Believe it or not Nylon trimmer line is Hygroscopic.

Trimmer line will lose moister and become brittle over the winter. Before the season starts drop that old spool of line in a bucket of water and let it sit. You will be surprised how it will help, works great for your fishing line to.

Also, if you find .065 or .080 line isn’t lasting long. I’ve modified my spools to accept .095 line. What a difference in its longevity!
