Customer Questions & Answers
-
Question:
What is a 750 CFM Double Pumper Mechanical Secondary Carburetor?
Answer: The 750 CFM Double Pumper Mechanical Secondary Carburetor is a high-performance carburetor designed for racing and performance engines. It features dual fuel inlets and mechanical secondaries that allow for quicker throttle response. This makes it ideal for applications where maximum airflow and performance are required, such as drag racing or street performance builds. Many enthusiasts utilize this carburetor to improve their vehicle's acceleration and overall power output. -
Question:
How does the mechanical secondary function in this carburetor?
Answer: In the 750 CFM Double Pumper, the mechanical secondary operates based on the throttle position. When the primary throttle opens, the secondary throttle plate follows, providing additional airflow at higher RPMs. This design ensures that the engine receives sufficient fuel and air mixture during demanding conditions. It's a preferred choice for applications needing strong acceleration and performance, especially in racing scenarios. -
Question:
What type of engines is this carburetor suitable for?
Answer: This carburetor is best suited for high-performance V8 engines, particularly those in racing or modified street cars. It is ideal for engines producing over 400 horsepower, as it can provide the required airflow and fuel delivery. If you have an engine that is built for performance, such as with upgraded camshafts, headers, or exhaust systems, this carburetor will enhance its efficiency and power output significantly. -
Question:
What are the benefits of using aluminum for this carburetor?
Answer: Aluminum is a lightweight material that offers superior heat dissipation compared to cast iron. This results in more stable fuel delivery and improved performance. Additionally, aluminum allows for intricate designs and less bulk, making the carburetor easier to install and adjust. This is particularly beneficial for performance applications, where weight and efficiency are crucial for optimal operation. -
Question:
Can this carburetor be used on street vehicles?
Answer: Yes, the 750 CFM Double Pumper can be used on street vehicles, but it is most effective on modified cars with larger engines and performance modifications. While it can enhance power for everyday driving, tuning may be necessary to achieve optimal air-fuel ratios for street use. Enthusiasts who want to add power to their high-performing street machines often opt for this carburetor to enhance their driving experience. -
Question:
What adjustments are needed for the 750 CFM Double Pumper?
Answer: Adjustment of the 750 CFM Double Pumper typically involves tuning the idle speed, air-fuel mixture screws, and possibly changing jets for your specific setup. Depending on your engine’s configuration, you might also need to adjust the float level or accelerator pump, ensuring the carburetor performs optimally at various driving conditions. Regular tuning can maximize performance, especially in racing setups. -
Question:
How does the fuel delivery system work in this carburetor?
Answer: The fuel delivery system in the 750 CFM Double Pumper comprises several key components, including the float bowl, jets, and fuel passages. When the throttle is pressed, fuel is drawn from the float bowl through jets into the engine’s intake manifold. The mechanical secondary adds extra fuel flow as needed, ensuring optimal performance during acceleration. This precise fuel delivery helps maintain power output and engine efficiency during demanding conditions. -
Question:
What is the typical installation process for this carburetor?
Answer: Installing the 750 CFM Double Pumper involves removing the existing carburetor and aligning the new carburetor with the intake manifold. You'll need to secure it properly with bolts, connect the throttle linkage, and attach the fuel lines. After installation, adjustments are usually necessary to tailor it to your vehicle’s specific needs. This process is manageable for those with mechanical experience, enhancing their engine's performance. -
Question:
What is the difference between a double pumper and a standard carburetor?
Answer: A double pumper carburetor features two barrels for fuel delivery, while standard carburetors might have only one. The double pumper allows for increased airflow and better performance under high RPMs, making it ideal for racing applications. In contrast, standard carburetors are better suited for regular driving conditions. Engaging a double pumper can significantly improve acceleration and overall engine output in performance-focused scenarios. -

Pateyney Carburetors YMXDM-1117BK Editorial Review
The customer experience with the carburetor has been a mixed bag, showcasing both impressive performance and notable issues. Many users have praised its functionality, highlighting that it runs well right out of the box, with one reviewer excited about testing it on the drag strip after installation. Customers have reported that the carburetor is lightweight and well-built, providing good value for the price. However, some users faced challenges that required immediate attention. A customer noted that a secondary float valve got stuck but managed to resolve the issue by replacing it with a spare. Another user encountered leaking jets that led to flooding in the carburetor, which affected their ability to return the product due to a late delivery. Additionally, a third reviewer experienced a sticking issue with the primary bowl caused by shipping-related impacts but found solutions mainly revolved around adjusting the idle air mixture screws and replacing gaskets for optimum performance. While there are clear performance advantages to this carburetor, be prepared for potential issues out of the box that may necessitate troubleshooting or modifications. **
