One of the main things a mechanic does, is replace or fix parts. There's so many moving components to an engine that something is almost always going to need repair. Some parts aren't meant to last forever, and usually need to be replaced after enough wear. But wear and tear isn't the only thing that causes pieces of an engine to malfunction. Time, weather conditions or accidents can cause a need for a replacement. I've repaired and replaced all kinds of parts, but here are the Top 5 of the most common ones that I see.

1. Tires:
While there are some small engines have solid wheels, like push mowers or pressure washers, many machines have inflated tires, and these don't last forever. They come in all shapes and sizes, and seem to be one of the most often parts of a machine to replace.
2. Fuel lines:
Hands down, the most common piece of a machine to crack, or dry-rot, fuel lines are absolutely necessary for an engine to work, and yet often need to be serviced.
3. Spark Plugs:
Most engines I work on have a malfunctioning or dirty spark plug. Whether the electrode is bent, or the terminal is corroded, I never fail to check the spark plug and clean it.
4. Carburetors:
Many times when an engine isn't running right, it could very well be a problem in the carburetor. It never hurts to take the bowl off, check the float or clean the jets. Oftentimes, the carburetor may be broken or malfunctioning requiring a necessary replacement.
5. Exhaust Systems:
Due to the heat and stress of the metal, exhaust systems are prone to cracking or breaking. While with some exhaust pipes, such as those on larger vehicles, you can get away will welding a crack or hole, small engines' exhaust pipes are considerably thinner, and therefore must simply be replaced.
