I just brought my fuel solenoid into the small engine repair shop and this is what i got. They told me my fuel solenoid is one, just a pain in the ass. It's supposed to prevent backfire or something of that nature. Two, it was very expensive to replace. I know that I had electrical and fuel both going to it. And I was burning fuel I put directly into the carb. So it had to be something in between which was this fuel solenoid. When I brought it in, it was funny to see that they just clipped the pin so that it didn't block fuel flow to the carb. This will however keep a constant fuel flow into the carb so I had to add a fuel shut off valve in the line before the solenoid. This should help with fuel problems with this expensive part. .
This part is what I call: PITA (pain in the @ss or MM (money maker) and when I diag mine to be defective (not worn out) I unscrewed it from the bottom carb bowl and removed a small seal at the end (pulled right off) and all is good now. Just overnight my engine would run out of fuel in about 30 minutes and restart after it cooled down.

Yes
It shuts off the fuel supply to the carb,they are spendy to buy so i just a different bolt where the solenoid was and the problem was cured. Additional: The solenoid is an important part of the safety system. No professional will tell you to bypass it because of the liabilities. The solenoid shuts off the fuel that go through the carburetor into the engine. It will shut off when there is a safety issue. It also shuts off with the key and helps prevent the engine from backfiring which can cause damage.
No, there is no bypass. If it becomes clogged the engine will not run.
The most simple way to bypass immobiliser is to drill out the bolts or do like i did and chisel off the black box on the back of the fuel pump. behind the black box you will find a fuel shut off solenoid ,put a live to the terminal (black and yellow wire that plugged into black box) you have now by passed the immobiliser
If you mean the stop solenoid it is on top of the fuel pump. The fuel pump is at the front of the engine bay on driver side.
Remove it first (typically just unscrews, may require narrow wrench and turning from the solenoid top). Determine the solenoid action (for example, when turning the key to on, does the solenoid have continuous power? Does the solenoid pin/plunger move up or down with power?). Permanently set the solenoid to allow fuel to flow, this can sometimes be done by cutting the pin/plunger part off, or pulling it out, there is a spring that may also need to be removed. Put the solenoid back in and make sure all seals are OK or add new ones. Note after bypassing a fuel solenoid, if you do not intent to replace it soon, you should install a fuel shut off valve when can be purchased from auto parts stores or big box hardware stores for 5-10 dollars. To prevent backfire, you would need to switch off the fuel and wait for the engine to stall which can take up to a few minutes. Turning the engine off with the key will still work, however you will not be protected from backfiring which can damage the engine. Turning the engine off by pulling the throttle back all the way will also not help.
Incorrect pump timing,low compression,fuel cut solenoid may not be working,
Turn the key off, shuts fuel off.
Back fire can be caused by improper ignition or the wrong fuel air mixture. With the engine off remove the air cleaner and look below it. If there is fuel in the pipe then the carburetor is not stopping the flow of fuel and it needs a rebuild.
on modern cars the fuel system is unvented. The evap purge and vent solenoid goes to a charcoal canister. When the vehicle is off the fuel tank is connected to the charcoal canister through the P/V solenoid and it absorbs the vented gas fumes from the tank. When the vehicle is on and at speed the solenoid switches and the charcoal canister is connected to engine vacuum and the vacuum of the engine purges the gas fumes in the charcoal through the engine burning them
The shut off electric solenoid is located on the very front of the engine, just above the fuel injection pump.. If you look at the front of engine looking back it will be on your left.. Bud
Sounds like a ignion coil.
