How to Spray Starter Fluid on a Lawnmower

Spraying starter fluid on your lawnmower is relatively easy, and the steps below make them more straightforward for you to follow.

  1. Firstly, you should remove the air filter cover from the lawnmower and clean it up.
  2. The next step is to also locate the carburetor and clean it so everything is in optimum condition.
  3. After you remove the air filter from its housing, take off the housing entirely also.
  4. Now, spray a dose of starter fluid directly into the carburetor chambers.
  5. Once you do this, you should set the engine speed to midpoint if the ideal is adjustable. However, when it is equipped, you should set the choke to full choke.
  6. Now, start your mower by pulling the starter string. If it has an electronic starter key, then use that.

Sometimes, the lawnmower starts and stops all within three seconds. In such a situation, then your carburetor is what requires adjustment. If the lawnmower starts for more than three seconds but doesn’t last up to thirty seconds, then it’s a case of bad fuel. Alternatively, the fuel could be water-saturated and need changing.

When to Spray Starter Fluid on a Lawnmower

Starter fluid is quite beneficial, especially in engines with a carburetor like a lawnmower. Many people use the starter fluid to determine what’s wrong with their lawnmower. The spray starter is an excellent diagnostic tool for discovering the issues with your lawnmower engine.

In winter, you should also spray starter fluid on a lawnmower if the machine finds it difficult to start. If the carburetor is in good condition, then a spray starter will ensure your engine starts instantly.

When Not to Spray Starter Fluid on a Lawnmower

You shouldn’t use starter fluid on diesel engines. On such occasions, it could significantly damage the lawnmower. Additionally, you shouldn’t use a starter spray on a 2-cycle gasoline engine. If there’s something wrong with the lawnmower, simply wait to get instructions from an expert.

Only use the starting fluid when the expert asks you to utilize it on the engine. A spray start is only ideal for carbureted engines because fuel can quickly vaporize through the tiny holes. If the gasoline does not evaporate in the cold, it could cause issues in your lawnmower engine. However, it usually ignites easily in the cold, which allows the engine to start and heat the fuel. 

If your lawn mower starts with starter fluid then dies, here’s a solution.
