Could a clogged fuel filter o r dirty carburetor cause sputtering in Suzuki Bolan?

My Bolan sputters especially when driving in traffic o r after starting from a stop. A friend said it might be due to a clogged fuel filter o r carburetor issues. How can I identify if this is the problem, and is it something that needs regular cleaning in Pakistan’s dusty conditions?

Yes, especially in older Bolan models with carburetor systems, a clogged fuel filter o r dirty carburetor is a major cause of sputtering, especially at low speeds o r when restarting after a stop.

How this happens:

Dirty fuel o r rust from the fuel tank blocks the filter o r carburetor jets

Inconsistent fuel flow causes engine hesitation

Carburetor might not spray fuel evenly due to dirt o r gum

How to tell:

Van sputters while accelerating from a stop

Engine stalls randomly, especially in traffic

You smell unburned fuel o r black smoke

Fix:

Replace the fuel filter should be done every 15,000–20,000 km in dusty areas

Clean the carburetor jets using carb cleaner

Use high-octane fuel occasionally to clean internal parts
