Holley Throttle Solenoid/Dashpot Bracket - Part #20-72

Add or replace your throttle solenoid or dashpot mounting with this universal Holley bracket. Designed for seamless integration with most Holley carburetors featuring universal throttle levers and threaded mounting holes, this bracket provides a secure, stable mounting point for throttle solenoids and dashpots, ensuring consistent idle control and smooth throttle operation.

Key Features:

• Universal Design: Fits most Holley carburetors with universal throttle lever
• Direct Mounting: Uses existing threaded holes in throttle body
• Dual Purpose: Accommodates both throttle solenoids and dashpots
• Genuine Holley Quality: OEM-grade bracket for reliable performance
• Secure Mounting: Provides stable platform for solenoid/dashpot operation
• Easy Installation: Bolts directly to carburetor throttle body

Performance Benefits:

• Provides secure mounting for idle speed control solenoids
• Ensures proper dashpot operation for smooth throttle closing
• Maintains consistent idle speed control
• Prevents vibration-related solenoid/dashpot issues
• Essential for emissions-controlled and air-conditioned vehicles
• Allows proper adjustment of solenoid/dashpot position

Understanding Solenoids and Dashpots:

• Throttle Solenoid: Raises idle speed when air conditioning is engaged or for emissions control
• Dashpot: Slows throttle closing to prevent stalling and reduce emissions
• Bracket Function: Provides adjustable mounting point for proper solenoid/dashpot positioning
• Emissions Importance: Required on many emissions-controlled vehicles
• A/C Applications: Prevents stalling when A/C compressor engages

Compatible Applications:

• Most Holley carburetors with universal throttle lever
• Carburetors with two threaded bracket mounting holes in throttle body
• Street performance and daily driver applications
• Emissions-controlled vehicles requiring idle speed control
• Air-conditioned vehicles needing idle speed compensation

Compatibility Notes:

• Compatible: Most Holley carburetors with universal throttle lever and threaded mounting holes
• Not Compatible: Model 0-1848-1 and Street Warrior series carburetors
• Verification: Check for two threaded holes in throttle body before ordering

When to Use:

• Installing throttle solenoid for A/C idle speed compensation
• Adding dashpot for emissions control or smooth throttle closing
• Replacing damaged or missing solenoid/dashpot bracket
• Converting to Holley carburetor on emissions-controlled vehicle
• Upgrading idle speed control system

Installation Tips:

• Verify carburetor has threaded mounting holes in throttle body
• Position bracket for proper solenoid/dashpot alignment with throttle lever
• Adjust solenoid/dashpot position for correct idle speed increase or throttle closing rate
• Ensure solenoid/dashpot doesn't interfere with throttle linkage operation
• Test A/C engagement or throttle closing operation after installation
• Secure all mounting hardware to prevent vibration loosening

Technical Specifications:

• Part Number: 20-72
• Type: Universal solenoid/dashpot mounting bracket
• Material: Steel
• Mounting: Bolts to threaded holes in carburetor throttle body
