Common Problems of Your Porsche 914 Carburetor

Your Porsche 914 carburetor is built to last a long time. But overtime, it develops different problems that are related to other faulty components. Carburetor problems like flooding, engine hesitation and fast or no idling are some of the most common that car owners with carburetors installed still experience. Below are the common carburetor problems and the troubleshooting steps to help you should you experience any of these:

Flooded carburetor

When your carburetor becomes flooded, there's a possibility that your engine will shut off or run roughly. The flooding happens when there is too much excess fuel pressure inside the carburetor, which can be caused by a faulty or broken fuel pump. Make sure to replace any worn fuel pump to avoid flooding. On the other hand, a stuck float can also cause the carburetor to flood. Simply tapping on the fuel inlet fixture can free up the float from getting stuck. You can also clean out the float bowls and needle passages of any dirt that has blocked the passage. You should also replace any worn or rusty parts and inspect whether your fuel tank is leaking. Immediate replacement of the worn parts can fix the problem.

Fast or no Idling

If your engine doesn't idle smoothly, idles too fast, or it stalls during idle when the engine is cold or warm, your car's carburetor is at fault. Normally, this is caused by a bad accelerator pump or power circuit. To fix this problem, you have to replace any worn components whether the carburetor or the accelerator pump. Also, you may just need to adjust the solenoids on the carburetor or completely replace them if they're already malfunctioning. Moreover, you can disassemble the carburetor to remove any trapped dirt or other elements inside to address this problem.

Engine hesitation

Engine hesitation can be caused by a carburetor, improperly connected vacuum hoses, or a clogged exhaust system. Also, a broken EGR valve or gasket can lead to this problem. These systems and parts must be inspected thoroughly and assessed whether they are still in good working condition. If not, you should replace any broken component to fix this problem.
