Choose the Right Spark Plug
Caution! Be sure to use the right spark plug! Although several different spark plugs may screw into the engine, using the incorrect one will result in performance problems and possible internal engine damage. Consult your owner’s manual or check your old spark plug for the manufacture part number and match our model fit guide for the right one you need.
Q&A on Spark Plugs
> Q: What is the function of a spark plug? A: A spark plug serves as a lighter to ignite the air-fuel mixture, creating the explosion which makes your engine produce power. A: > Q: How do I know if I need new spark plugs? An engine that hesitates, misfires, or has rough idling instead of running smoothly may be attributed to faulty spark plugs. Also, a sudden drop in fuel economy can be traced to dirty or fouled spark plugs. If the spark plugs aren’t functioning properly, it can have a negative impact on your fuel consumption. > Q: How often should spark plugs be replaced? A: The standard life of a lawn mower spark plug is 25 hours. It doesn't matter how well you take care of your lawn mower, spark plugs wear out after about a season's use. > Q: How do I choose the right spark plug?A: There are many factors to consider such as dimensions and heat range. The easiest way to identify the right spark plug is to search your model at our search bar or email your model to firstname.lastname@example.org for recommendations. > Q: What happens if I don't change spark plugs? A: Spark plugs will depreciate over time, so various engine issues will arise if they are not replaced. When the spark plugs do not generate an adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run. > Q: What happens if you don’t gap your spark plugs? A: If the gap on your spark plug isn’t set to the correct specification, you might get misfires or knock or see carbon build-up or excess fuel. Always check if the gap is correct.
Hipa Brand Story
How Hipa Began
While traveling in the US, I stayed with an old friend. He enjoyed maintaining his home and garden and was good at DIY. One Saturday, he wanted to mow his yard before we went to lunch but soon after I noticed he was having trouble starting his mower. After ... spending some time, he finally decided the likely culprit was that the carburetor needed replaced and grass and debris had clogged the air filter. After searching for the parts, he soon became even more frustrated and confused. He found the listings did not address the main problems, and the title and descriptions presented confused or even conflicted information. There was also often no way of determining quality or compatibility, or even an explanation of how to choose the correct part. What should have been a simple task of finding the right part was nerve wracking and time-consuming and there was often no way to verify beforehand, even the part was correct, that would also cause further delays in our already hectic lives. Inspired by this unpleasant repair ordeal, I developed an idea to offer all-in-one repair kits to simplify the process of finding the right parts. Customers can save time and money, keep their maintenance schedules timely and organized, and only perform repairs once. Hipa was born of this vision to help our customers get their job done right, the first time. How We Developed
