FULL DESCRIPTION
Keyster Press Fit Slow Jet - Size 40
Restore proper fuel mixture and engine performance with this Keyster press fit slow jet. Designed as a direct replacement for pressed-in slow jets found in various carburetors, these jets are essential for maintaining optimal engine operation at idle and low speeds.
Many carburetors from the 1970s and 1980s feature slow jets that are permanently pressed into the carburetor body. When these jets become clogged or damaged, they can be difficult or impossible to replace with OEM parts, often leading to carburetor replacement. Keyster press fit slow jets provide a solution by allowing for the removal of the old jet and the installation of a brand new one, enabling thorough carburetor cleaning and restoration.
Key Features:
- Press Fit Design: Specifically engineered to replace original pressed-in slow jets.
- Size 40: Precise jet sizing for accurate fuel delivery.
- High-Quality Construction: Manufactured for durability and reliable performance.
- Sold in Packs of 5: Convenient multi-pack for multiple carburetors or future needs.
- Carburetor Restoration: Enables proper cleaning and rebuilding of carburetors where original slow jets are no longer serviceable.
