Comprehensive Carburettor Services

Whether you require an on-vehicle or off-vehicle* overhaul, our team of highly skilled technicians is well-equipped to handle any and all of your carburettor servicing needs. We pride ourselves on offering a comprehensive range of services, including in-depth engine tune-ups, pre-purchase inspections, safety assessments, and complete vehicle servicing tailored to an extensive variety of vehicle models. Our expertise goes far beyond mere cleaning; we adopt a diagnostic-driven approach that allows us to meticulously identify and rectify any underlying fuel system complications. This thorough process ensures not only immediate improvements but also long-term reliability and performance of your vehicle.

For automotive enthusiasts who have modified their engines, we offer specialised carburettor conversions, tuning, and re-jetting services. These services are designed to facilitate seamless integration with your performance upgrades, ensuring that your vehicle operates at its best. Each adjustment we make is executed with precision and care, aimed at achieving maximum efficiency, enhanced power output, and improved throttle response.

* It is important to note that diagnosing fuel delivery and tuning issues is most effective when conducted through an on-vehicle assessment. Many fuel system problems can arise from a complex interplay of multiple factors, rather than being solely attributed to the carburettor itself. By performing on-vehicle tuning, we can achieve the most accurate results, allowing us to fine-tune your vehicle for optimal performance. This hands-on approach not only enhances the driving experience but also contributes to the longevity of your engine. Trust us to provide the expertise and attention to detail that your vehicle deserves, ensuring it runs smoothly and efficiently for years to come.

Carburation is Just One Part of Performance

A petrol engine relies on five fundamental elements to operate efficiently. Diagnosing performance-related issues requires an understanding of how these factors interact. Addressing each of these key areas can yield substantial improvements in power, efficiency, and overall reliability:

1. Air:

Clogged Air Filters:

One of the simplest yet most crucial maintenance tasks is ensuring a clean air filter. Over time, dirt, dust, and debris can accumulate, restricting airflow to the engine. A clogged filter forces the engine to work harder, leading to reduced power and increased fuel consumption.

Exhaust Flow Obstructions:

Just as air intake is critical, an unrestricted exhaust system is equally essential. Blockages in the exhaust, such as deteriorating catalytic converters, damaged mufflers, or excessive carbon buildup, can drastically reduce performance by limiting airflow.

Valvetrain Wear and Deterioration:

Engines without hydraulic lifters may experience gradual wear in their valvetrain components. Over time, this can lead to misadjusted valve clearances, resulting in compromised airflow, inefficient combustion, and a noticeable drop in power.

2. Fuel:

Inadequate fuel delivery can severely impact power, particularly when the engine demands more fuel than the system is capable of supplying.

Fuel Pump Wear:

As fuel pumps age, their efficiency can decline, leading to insufficient fuel pressure during high-demand scenarios such as acceleration or hill climbs. This may result in hesitation, stalling, or an overall sluggish response.

3. Spark:

Carbon Deposits on Pistons:

The buildup of carbon deposits can lead to abnormal combustion events, such as engine knocking. The engine may compensate by retarding ignition timing, which in turn reduces power output.

Fouled Spark Plugs:

Dirty or worn-out spark plugs can result in weak or inconsistent ignition, leading to misfires, rough idling, and diminished fuel efficiency.

4. Compression:

Maintaining proper cylinder compression is essential, especially in older engines. Loss of compression due to worn-out components can significantly hinder performance.

Piston Ring Wear:

Over time, piston rings may wear down, causing excessive blow-by and reduced power. This condition can also lead to increased oil consumption and contamination from combustion byproducts.

Carbon Buildup on Valves:

Accumulated carbon deposits on intake and exhaust valves can prevent a proper seal, leading to compression loss and potential misfires.

5. Friction:

Regular oil changes are essential to reducing internal friction. As oil ages, it breaks down, leading to increased resistance, which in turn places additional strain on engine components.

Routine maintenance is key to sustaining engine performance. While wear and tear are inevitable over time, proper servicing can dramatically prolong the lifespan and efficiency of your vehicle.

Carburettor Servicing Process

We follow a structured approach to carburettor servicing, ensuring that every unit is returned to optimal condition. The process includes:

1. Inspection and Diagnostics:
   • Visual Inspection: Examine the carburettor for signs of wear, damage, or dirt buildup.
   • Functional Check: Test the choke, throttle operation, and idle settings to identify any immediate issues.
   • Assessing Vehicle Symptoms: Consider any problems the vehicle has been having, such as difficulty starting, rough idling, or stalling.
2. Removal:
   • Safety Measures: Disconnect the battery and ensure the vehicle is in a safe, stable condition.
   • Detach Components: Carefully disconnect fuel lines, linkages, and remove the air cleaner.
   • Carburettor Removal: Unscrew and gently lift the carburettor from the manifold.
3. Disassembly:
   • Component Cataloging: We methodically disassemble the carburettor, keeping track of all parts and their placements.
   • Gasket and Seal Removal: Remove old gaskets, seals, and o-rings that will be replaced. Inspect for witness marks. Temporarily retain for identification purposes.
4. Cleaning:
   • Soaking and Scrubbing: We use specialised cleaners to soak and clean all metal components. Non-metal parts should be cleaned separately to avoid damage. 
   • Ultrasonic Cleaning: Some parts may require ultrasonic cleaning to remove stubborn deposits.
   • Air Blowing: Use compressed air to blow out all passages and ensure all parts are completely dry.
5. Inspection and Repair:
   • Wear and Tear Check: Inspect all parts for wear, cracks, or other damage.
   • Replacing Components: Replace any worn or damaged parts with new ones. This often includes jets, needles, gaskets, and seals.
   • Surface Check: Ensure mating surfaces are clean and flat for a proper seal.
6. Reassembly:
   • Gasket and Seal Placement: Install new gaskets, seals, and o-rings.
   • Component Reassembly: Carefully reassemble the carburettor, ensuring all parts are correctly aligned and secured.
   • Adjustments: Set the initial adjustments for idle, mixture, and choke based on manufacturer specifications.
7. Installation:
   • Mount Carburettor: Place the carburettor back onto the manifold, ensuring a proper seal.
     Reconnect Components: Reattach fuel lines, linkages, and the air cleaner.
   • Safety Check: Ensure all connections are secure and there are no leaks.
8. Adjustment and Tuning:
   • Idle Setting: Start the engine and adjust the idle speed and mixture screws for optimal performance.
   • Performance Testing: Test the throttle response, acceleration, and deceleration.
   • Final Checks: Look for any signs of leaks or abnormal behavior.
9. Road Test:
   • Driving Test: Take the vehicle for a drive to ensure it performs well under various conditions.
   • Monitoring Performance: Pay attention to engine responsiveness, idling stability, and overall performance.
10. Post-Service Inspection:
    • Recheck: After the road test, reinspect the carburettor and surrounding area for any issues like leaks or loose components.
    • Final Adjustments: Make any necessary final adjustments to the carburettor settings.

This procedure requires not only technical know-how but also a keen attention to detail and patience. It's vital to follow the manufacturer's specifications and use the right tools and parts for the job. For someone inexperienced with classic cars or carburettors, we reccommend that you use our professional help to ensure the best care for your vehicle.
