The arrow on the primer bulb should be pointed in the direction of fuel flow. The primer bulb should have an arrow pointing in the direction of fire. If the arrow is pointing away from the ignition source, it means that the fuel is not flowing into the combustion chamber. The spark plugs need to be replaced.
If you hear a popping sound when you turn on your car, or see smoke coming out of the exhaust system, you may have a sparkplug problem. Spark plugs are made of metal, and if they are not in good condition, they will not work properly.
You can check the condition of your ignition coil by turning it on and off a few times to make sure that it doesn’t get too hot or too cold. It is also a good idea to replace the coil with a new one if it has been sitting around for a long time.

Is primer bulb necessary?
A primer bulb is important because it is helps to fill the carburetor with the correct amount of fuel. The fuel line is pulled through by it. If your primer bulb isn’t creating enough pressure to push fuel into the cylinder, you may need to replace it. The fuel pressure is too low to allow fuel to flow through.
This can be caused by a leak in your fuel system, a fuel filter, or a problem with your engine’s fuel injection system. If you have an aftermarket fuel injector, you may have to replace it with a new one. Check to make sure that it has the same type of nozzle as the one you are replacing.
The new nozzle should have a larger diameter than the old one, so it will be able to pull fuel out of your cylinder more easily. Also, check to see if the new fuel nozzle has a plug on the end of it to prevent fuel from leaking out.
A plug is a small piece of metal or plastic that fits into a hole in the nozzle to hold it in place. When you remove the plug, fuel will leak out, and you will have no way to get it back in. If you do not have any of these problems, then you should be good to go.
Why is my primer bulb not working?
If the primer bulb isn’t working, it may be a problem with the bulb itself, with the fuel lines that feed fuel to the bulb or both. Primer bulbs and tubes are made of flexible plastic or rubber, which will eventually crack or break.
If you’re not sure what type of bulb you have, you can check it out at your local auto parts store. If you don’t have a local store, check with your dealer or the manufacturer’s website.
Which fuel line goes to the primer bulb?
The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. If you don’t have a clear fuel line, you’ll need to buy one. You can find them at most auto parts stores, or you can make your own.
Where should primer bulb be on outboard?
The primer bulb, located in the fuel line between the gas tank and the engine, is used to fill the carburetor when the engine is started cold. The rubber bulb is oblong in shape. The amount of fuel that is injected into the combustion chamber is controlled by two valves inside the bulb.
When the valve is closed, fuel is not injected, and when it is opened, it allows fuel to be injected. When the ignition switch is turned to the “on” position, the two fuel valves are opened and closed. This causes the piston to move back and forth inside the cylinder until it reaches a certain point.
At this point, a spark ignites the mixture of gasoline and air. As the pistons move forward, air is forced out of the cylinders, causing them to expand and fill with gasoline. If the spark does not ignite, gasoline will not be able to flow through the valves and ignite the gasoline mixture.
Can you over Prime an engine?
Pumping the primer too many times can lead to overpriming the engine. Excess fuel can be sprayed into the engine cylinder and cause a fire if it drips onto the exhaust manifolds. If you smell fuel, stop, you may have overprimed your engine and need to start over.
