Finding the Source of the Problem: Troubleshooting Your Mazda B2200 Carburetor
Achieving optimum combustion should be a piece of cake if you have a good Mazda B2200 carburetor under your hood. Generally, this crucial engine part is built to last, but it will also wear out and function poorly over time. If you feel your Mazda's not getting its regular dose of air and fuel mixture, then you had better do some troubleshooting real fast before your engine sputters and dies in the middle of the road. A faulty carburetor will cause serious air and fuel delivery problems that can throw the combustion operation off track and hamper your vehicle's performance. If your carburetor's acting up, a bit of troubleshooting can help you find the source of the problem. We've come up with a quick and easy guide to help you out.
If your engine's cranking but not starting, then you probably have a flooded carburetor. Excess fuel pressure is most likely the culprit behind this problem, but this can be easily solved by replacing your worn-out or defective fuel pump. A stuck choke may also cause hard starting and carburetor flooding, as this blocks the flow of air to the engine. You may simply tap the fuel inlet fixture to correct this problem. If all else fails, replace the flooded carburetor.
If you're experiencing engine hesitation, you need to check on the vacuum hoses and your exhaust system. Vacuum hoses that are not connected properly will cause the carburetor to malfunction, resulting in engine hesitation. Before attempting to replace your carburetor, connect these hoses properly and see if this makes any difference when you accelerate. If you've ruled out vacuum hose connection problems, next on your list should be your exhaust system. Make sure it's not clogged to prevent the carburetor from malfunctioning. Lastly, check your EGR valve for damage. A faulty EGR valve may also cause your engine to hesitate, so replace it if necessary.
Rough idling is sometimes caused by incorrectly adjusted carburetor screws. To fix this problem, simply correct the screws' adjustment. Properly adjusted carburetor screws will help prevent rough idling and allow your vehicle to run more efficiently.
