FAQ – Vintage Parts and Carburetors
How do I know if a part is compatible with my carburetor?
Compatibility depends on the exact model of the carburetor (Weber, Solex, Dellorto, etc.) as well as its precise reference. Before ordering, always check the carburetor's reference or compare it with the original part. If in doubt, do not hesitate to contact us for confirmation.
What are the signs that a carburetor needs an overhaul?
Several symptoms may indicate that an overhaul is necessary:
- unstable idle
- starting difficulties
- fuel leak
- engine stalling when stopped
- excessive consumption
In this case, cleaning and replacement of wear parts (gaskets, needle valve, jets) may be necessary.
What is the difference between a gasket kit and a complete overhaul?
A gasket kit allows for replacing the carburetor gaskets during disassembly or maintenance.
A complete overhaul may also include replacing other parts such as the needle valve, jets, or float, depending on the condition of the carburetor.
Are the parts sold compatible with original carburetors?
The parts offered are intended for the maintenance and restoration of carburetors used on vintage and classic automobiles. They generally allow for replacing worn original parts and restoring the carburetor to working order.
Is it possible to restore an old carburetor?
Yes, in most cases an old carburetor can be restored.
A complete disassembly, thorough cleaning, and replacement of wear parts often allow for a return to near-original operation.
Do you offer a carburetor cleaning or restoration service?
Yes, we offer a carburetor cleaning and restoration package. This service allows for restoring old carburetors by replacing necessary parts and performing a complete cleaning.
How long does shipping of parts take?
Orders are prepared and shipped from France. Lead times may vary depending on part availability and the chosen carrier.
Can I contact you to identify my carburetor?
Yes, if you have any doubts about identifying your carburetor or the part to order, you can contact us before purchase. We can help you identify the correct model and part.
How to identify a Weber, Solex or Dellorto carburetor?
The carburetor reference is usually engraved on the carburetor body or on a small plate. This reference allows for precise identification of the model (for example, Weber DCOE, Solex 32 TDID or Dellorto DRLA) and selection of compatible parts.
Why is my carburetor leaking fuel?
A fuel leak can be caused by several factors:
- a worn or stuck needle valve
- a defective float
- deteriorated gaskets
- an incorrect fuel level
In most cases, a carburetor overhaul with replacement of wear parts can resolve the problem.
Why is my engine idling unstable?
An irregular idle can have several causes:
- clogged jets
- air leak at the carburetor
- incorrect air/fuel mixture adjustment
- wear of certain internal parts
Carburetor cleaning and correct adjustment often improve idle stability.
What is the function of jets in a carburetor?
Jets regulate the amount of fuel sent into the engine. Depending on their size and type (main jet, idle jet, air jet), they influence the air/fuel mixture and thus the engine's operation.
What is the difference between Weber, Solex, and Dellorto carburetors?
These three manufacturers are among the best known in the field of automotive carburetors:
-
Weber is renowned for its sports carburetors like the DCOE or IDF
-
Solex has equipped many European production engines
-
Dellorto is often used on sports engines or engine preparations
Each brand has its own models and carburation characteristics.
Can engine performance be improved with a carburetor?
Yes, certain carburetors like the Weber DCOE or Dellorto DRLA are often used in engine tuning to improve performance. However, proper adjustment and adapted configuration are essential to achieve optimal operation.
Why is cleaning a carburetor important?
Over time, deposits can form in the carburetor's passages. These deposits can disrupt carburation and cause:
- starting difficulties
- irregular idle
- poor throttle response
A complete cleaning restores the carburetor's proper functioning.
Can old carburetors still be repaired?
Yes, in most cases old carburetors can be restored. Replacing wear parts such as gaskets, needle valves, or certain jets often extends their lifespan and restores reliable operation.
