Common Carburetor Issues
Before diving into troubleshooting, it's essential to identify some of the most frequent problems that carburetors can experience:
- Engine Won't Start: This can be due to a variety of carburetor issues like clogged jets or improper fuel mixture.
- Rough Idling: This occurs when the engine runs unevenly at idle speed, possibly caused by a dirty carburetor or incorrect idle speed adjustment.
- Poor Engine Performance: Loss of power or acceleration can be symptomatic of blockages or misadjustments in the carburetor.
- Flooding: When too much fuel is delivered to the engine, it can lead to flooding, often indicated by a strong smell of gasoline.
- Backfiring: This can happen if the carburetor delivers a lean mixture, causing the engine to backfire.
