Experienced gardeners share their insights in answering this question :
A couple of questions first, when you replaced the plug, did you use a Champion RCJ6Y? When you changed the gas lines and filter, did you make sure you put the lines in the correct order (there are 2 lines, one is a supply the other is a return…the supply is usually a smaller diameter than the return and should connect to the bottom port of the carburetor), did you check the cap (there is a filter and a check valve in there, if faulty the cap needs to be replaced)…

Incorrect fuel mixture can cause the Blower to not start or run roughly, make sure you are using the correct fuel mixture with your blower. Ryobi Blowers run off a 50:1 ratio, this means 50 parts unleaded fuel to 1 part 2-stroke oil. The choke being left on will cause your Blower to not run correctly and shut off.
First remove and reinsert the battery to ensure that it`s seated properly in the Blower. If this doesn`t work, check the battery charge level by pushing the battery indicator button. If the battery is low, stop and charge the battery before use.
The carburetor or fuel filter might be clogged.

First, check the carburetor to see what has happened. If it`s clogged, there are three options: clean the carburetor, rebuild it, or replace it entirely. If a clogged fuel filter is the source of the issue, you`ll likely need to replace it.

Check the spark plug

If your leaf blower runs on petrol and won`t start, the spark plug might be faulty. Typically it needs to be changed every year but can be done sooner with high usage. Start by unclipping and giving it a clean using plug-specific cleaner and a wire brush.

Blower motors are designed to circulate air, so they won`t work if there`s no air to move. You should always check the filters and vents surrounding the blower to make sure that the blower isn`t having a hard time working. Look into your air filter`s housing and check the markings on your filter.
If your blower is having a difficult time starting, then you may be dealing with a carburetor issue. The carburetor`s job is to ensure the proper mix of fuel and air is directed to the blower`s engine. As mentioned, the carburetor can become clogged, making it difficult for fuel and air to enter the engine.
If your leaf blower engine is lacking power, it could be due to a blocked air filter. A plugged air filter will restrict air flow into the engine, reducing power and performance. Changing the air filter is an easy fix, and should solve this issue.
To completely start over the game, including all challenge progress, go to Options > Misc > Hard reset. The same result can be achieved by deleting the save. dat file. This will also reset options, which you can preserve by copying options.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
The fuel lines on your blower carry fuel from the tank to the engine. If these fuel lines are obstructed, it can`t allow the proper amount of fuel to enter the engine, which will cause it to run for a short time, but ultimately stall out. You may be able to clean out the fuel lines and solve this problem.
Dirty or Worn Spark Plug

Among the first things to check if your trimmer won`t start is the spark plug. In some cases, the spark plug may simply be dirty and need a thorough cleaning. To clean your spark plug, disconnect it and clean the area around it before removing it, advises Briggs and Stratton.
