But first, we will assume you want to know about carburetor and choke and their function on the snow blower. Skip this part if you want to fix the problem quickly.
What Is Carburetor
A carburetor is an essential component in an internal combustion engine. It is responsible for mixing fuel and air in the right proportions and supplying the mixture to the engine.
In fact, the carburetor regulates the amount of air and fuel that are mixed together, which affects the speed and power of the engine. The carb also helps to control the engine’s idle speed.
What is a Choke and how its function on the engine?
Like all small engines, a choke is a valve in the snowblower to restrict the airflow into an engine in order to make it easier to start.
When the engine is cold, the choke is used to partially or fully block the flow of air. This increases the fuel concentration in the combustion chamber thus leading to a quick and easy engine start-up.
This is designed especially for cold conditions when your small engine won’t start easily. Once the engine is warm, the choke is no longer needed and can be turned off.
YardMax Snow Blower Won’t Stay Running: Causes and Solutions
If your YardMax snow thrower engine won’t start or won’t stay running when you pull off the choke, there are several reasons and causes.
A blocked carburetor can result in the use of a choke in a snow blower to immediately start it. As the carburetor is responsible for mixing the air and fuel in the engine if it gets blocked, it can cause the engine to run lean or don’t run at all, meaning that there is not enough fuel being mixed with the air.
This can cause the engine to stall, and the YardMax snow thrower will need to be choked to get it started again. But choking is not the best option all the time, you should clean the carb. Before going to clean this thing, it is important to know why the carb gets blocked.
A carburetor can become blocked for a number of reasons.
They typically get blocked due to old or stale gas, which reduces the carburetor efficiency and causes engine problems.
When gas sits for too long, it begins to break down and form deposits on the carburetor. This old gas can become stale and turn into varnish, which can also clog up the carburetor’s jets and passages.
If there is somehow water in the gas, it can also cause deposits to form.
Moreover, moisture can condense in the carburetor, which can lead to rust and corrosion.
Note: Gas is considered damaging for caburetor and engine if it is more than 5-6 months old. Therefore, never use old gas in your small engines, if you dont want your machines to end up running on just choke.
Another common reason maybe is if the snow blower is left outside in the cold for an extended period of time. The cold weather can cause the carburetor to freeze, which can then block the fuel line and prevent the snow blower from starting.
Another reason a carb can become blocked is if there is debris in the fuel line. This can happen if the fuel is of low quality, or the fuel line is not cleaned regularly. The debris can clog the carb and prevent the snow blower from starting.
