If you have ever attempted to start a 2-cycle engine, you know — as on a lawnmower or a weed eater — that it can be difficult at times. That's because the engine requires a specific blend of gas and air to function properly. Finding the right mix can be a challenge, particularly if you’re not well-versed on how it works. Thats where a primer bulb comes in to lend you a hand!
A primer bulb is a small, rubber button that you squeeze. It helps knowledge gas your engine up when you press this button. Squeezing the primer bulb causes gas and air to fill it up. This extra gas and air is huge since it allows your engine to start better. This is particularly useful when it's cold outside since it can be more challenging to get the engine going in those conditions.
The first step to starting your 2-cycle engine is to press the primer bulb a couple of times. It directs gas and air into the engine for a little extra push. Once you have caught it, you will then want to attempt to crank the engine as you would typically do. For many people, using the primer bulb will make their engine start a lot faster and easier than without it. This is such an easy step that makes a huge impact!
There are three key components to your 2-cycle engine primer bulb: the bulb, the base, and the fuel line. That rubber button that you squeeze to pump gas into the engine is the bulb. The base is the plastic piece that keeps the bulb immobile so that it does not slide or move around. Our third part is the fuel line, which connects the bulb to the engine. This line sends the mix of gas and air into the engine, which is then required for it to function appropriately.
There are some issues with the primer bulbs that can leave them ineffective. The most frequent problem is that the bulb will slowly crack or break with time. Should that happen, you would need to pull out the bulb and insert new one to ensure that your engine starts properly. The other issue your tractor would have is if the fuel line got damaged or disconnected. A defective fuel line can prevent the bulb from functioning properly. In those cases, replacing the fuel line is required to seal the problem. Finally, if dirt or debris clogs your primer bulb, you can pop it off and clean it. Cleaning with a small wire brush will help you to remove any blockages of the bulb to make it work better.
Keep in mind that not all primer bulbs are created equal. And it means you must select the one appropriate for your particular engine. You will need to know the make and model of the engine to do this. This information can guide you in selecting the appropriately sized primer bulb. It’s also wise to inspect the size of the fuel line that connects the bulb to the engine. There are various sizes and the effective working of every other thing is also based on the correct sizes.
