Happy mowing!

Very rarely is the spark plug ever a cause of failure. In all the years I have been doing small engine repair, this is only the second time a spark plug was the cause of a no start.

Carbon build up on the on the center electrode eventually reached the side electrode filling in the spark plug gap and causing a loss of spark.

This excessive carbon build up on the spark plug was likely due to the mower being run on a dirty/clogged air filter causing the engine to run rich (too much fuel) because of restricted air flow through the intake.

This is why doing preventative maintenance is important! Especially on lawn mowers that are up against both dirt and heat!

Outboard motor carburetor cleaning. Float needle stuck. Emulsion tube clogged. Let’s see how this cleans up in the ultrasonic cleaning tank!

If you have a Honda lawn mower or a lawn mower with a Honda engine, check the clips on the air filter box.

The cover hinges on the bottom and snaps in on top. When the cover is snapped in, it seals the air filter.

If one of the clips are broken, the air filter will not seal. This can become very problematic, especially on a lawn mower that generates dust when you operate it.

The engine will be ingesting dirt and this will eventually score the cylinder and cause a loss of compression. Sufficient compression is a critical factor in order for an engine to run.

This is a fairly simple fix that can save you a lot!
