Can the fuel shut off solenoid be replaced on a 15.5 ohv briggs more
Sounds like a fuel issue. Does your mower restart immediately after it stalls? For those 20 seconds the engine actually runs or is it stalling etc.? I'd start with considering a stuck float.
Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
Glad you got it fixed without having to disassemble anything. here
The only option is to replace it with a new part. These are generally inexpensive and easy to get. [links]
You can check the ignition coil with an ignition system tester, a cheap device that you can buy at the hardware store. Follow the following steps: more
Broken Priming Bulb and Worn-Out Carburetor: [links]
In the case that you have an electrical trimmer sometimes the fault is the most obvious one and that is the power source. [links]
The carburetor is an essential part of the engine and is the main reason your machine starts. That means if there’s a problem with it then you won’t be able to get your engine started. The problems that can occur with the carburetor include: here
If you leave the trimmer full of gas when you store it for the winter, the fuel partially evaporates, leaving behind a sludge that resembles varnish. This sludge can partially block the inlet ports for the carburetor. Consequently, there may be enough fuel in the carburetor to start the engine, but there may not be enough to keep it running. You can prevent this from happening by adding fuel stabilizer to the gas tank before you store the trimmer, but once the carburetor is blocked, there's no alternative to cleaning or replacing it.
The engine draws air into the combustion chamber through the intake port, and if the air filter is dirty, combustion is partial and the trimmer will sputter and die. The air filter is readily removable, and replacements are inexpensive. Similarly, air must exit through the exhaust port, and that is covered by a spark arrestor to prevent fires. When the spark arrestor is clogged, the engine can't get rid of its exhaust gases, and it won't keep running. The spark arrestor is a screen located just behind the muffler. Pull it out and clean or replace it.
While it can be a delicate task to disassemble a carburetor for a complete cleaning, you usually don't have to do that to remove deposits from old fuel. The first step, after you've located the carburetor, is to drain the float bowl. After unscrewing and removing it from the trimmer, spray it generously with carburetor cleaner, being sure to direct the cleaner through all the port orifices. If the trimmer doesn't run smoothly after doing this, disassemble for a more thorough cleaning. It's probably best to take the carburetor to a service professional for this.
The gas cap on most trimmer has a small air inlet hole that allows air to enter the fuel tank, preventing a vacuum from forming as fuel sprays into the carburetor. It's easy to check whether or not this hole is blocked -- just loosen the cap and see if the trimmer operation improves. If it does, it's time to replace the gas cap. The fuel system also includes a filter that can clog. It's difficult to determine visually whether or not it's blocked, but it's easy and inexpensive to replace. You should do this as part of regular maintenance.
The two-cycle engine that runs your string trimmer needs three things to operate smoothly: clean fuel, air circulation and a spark. The engine won't start if any of these elements are missing, but it may run for a short time if only the air or fuel flow is restricted. It isn't difficult to restore air circulation, but if the fuel flow is restricted, you may need to disassemble the carburetor and clean it.
If there is no damage or sign of wear, you can skip the replacement step. more
A 4-cycle trimmer has a higher level of fuel efficiency. As a result, it uses less fuel, energy and has a high level of output. However, it is heavy when compared to smaller 2-cycle trimmers.
The most common issue comes from a clogged carburetor. It comes from leaving fuel in the trimmer over a long period. You can clean this with any standard carburetor cleaner. Also, you may have to replace the gas. If all else fails, you will need to replace the carburetor.
The spark arrestor is located near your muffler and prevents your engine from sparking. Over time, a spark arrestor builds up a thick layer of soot, which stops your muffler from exhausting. here
