Porsche 924 Carburetor

Porsche 924 Carburetor: Common Problems and Their Causes

One of the most important parts of your Porsche 924 is the carburetor. This part is responsible for keeping your vehicle in tip-top shape by supplying the right fuel and air ratio to the engine. However, although it is typically made from high-quality materials, it will eventually get damaged due to constant exposure to varying temperatures and every day use. So, if you think that your vehicle has a faulty carburetor, you need to check it pronto to avoid complications. Check out the list below for some of the common problems that you may encounter with your Porsche 924 carburetor.

Engine hesitation when accelerating

If your Porsche 924's engine is hesitating or stumbling whenever you are trying to accelerate, then there's a big chance that the carburetor is misadjusted or needs to be cleaned. Usually, because the carburetor is clogged by fuel varnish deposits and other kinds of debris, the flow of fuel becomes restricted, therefore causing the engine to stumble. To check if this is the problem, just uninstall the carburetor, and inspect it visually.

Below par fuel economy

An unexplained dip in fuel economy may be caused by a heavy or wrongly set carburetor float. If the float is made from foam plastic, check if it is too saturated with fuel by weighing it. However, if the float is not the problem, and the carburetor has been recently changed, then you have to make sure that the jets are not too small or too big for your vehicle.

Rough idle

In case your Porsche has developed a rough idle condition, then you have to check if there are air leaks between the intake manifold and carburetor. These air leaks are typically caused by loose bolts at the base of the carburetor or a worn-out gasket. If this is the case, just replace the gasket or tighten the bolts.

Ignition difficulties

Your vehicle may be experiencing ignition problems because of a carburetor choke that doesn't close, therefore making the fuel mixture too rich. If this is the problem, you don't have to replace the entire carburetor. Just purchase a choke repair kit to solve the ignition problems.

  • Three Tips on How to Keep Your Porsche 924 Carburetor in Tip-top Shape 04 March 2014

    One of the most important parts installed in your Porsche 924 is the carburetor. Also known as the "heart" of the vehicle, this part is responsible for delivering the right amount of fuel and air mixture to the engine. Once the carburetor gets damaged or contaminated, your vehicle may experience ignition, acceleration, and transmission problems. To avoid these complications, follow the tips listed below on how to keep your carburetor performing at its best.

    • Use the right carbuertor cleaner.
    • Nowadays, many kinds of cleaners can be used to remove grime buildup on your vehicle's carburetor. One type that you can use if you are in a hurry is the spray-type carburetor cleaner. This solution only needs to be carefully sprayed on the dirty surface then cleaned off using a metal brush or shop rag.However, if the carburetor is too dirty, then you should use the soak-type cleaner. This solution is typically sold in a gallon-sized can and comes with a plastic bucket or basket. Just soak the carburetor in the cleaner-filled bucket for a few minutes to soften and remove the grime.In case these cleaners are unavailable, then you can use an ordinary brake cleaner. Though it is designed to clean brakes, it can also dissolve dirt just like carburetor cleaners.
    • Rebuild your carburetor.
    • Rebuilding or replacing the faulty parts of your vehicle's carburetor is another way to make this part last for a long time. Done with the help of a rebuild kit, this should be done at least once a year to keep the carburetor in perfect condition. However, keep in mind that the right kit for your vehicle's make and model should be purchased to avoid long-term problems. What's more, the instructions indicated in your car's service manual should be followed step-by-step because not all carburetors are made the same.
    • Inspect the carburetor regularly for damages.
    • To avoid problems caused by a damaged carburetor, regularly check the part for damages such as loose bolts, worn-out gaskets, and air leaks. Although these are just minor components, they can still cause a truckload of trouble such as rough idling and hard starting if not checked properly.
