Joworthy Carburetor Throttle Ball Assortment for Holley 20-2 — 2 Sets, Precision Steel Balls & Studs

Joworthy's 2 Sets Carburetor Throttle Ball Assortment is a ready-to-install replacement kit of precision-machined steel throttle balls and lever studs made to fit Holley 20-2 carburetors.

When restoring, repairing, or upgrading a Holley 20-2 carburetor, small linkage parts like throttle balls and studs are critical for smooth, reliable throttle action. This kit supplies two complete assortments with multiple sizes so you can match worn or missing parts without long lead times. Each component is machined and polished to minimize play and resist wear under heat and vibration typical of engine bays.

What parts are included and why does the assortment matter?

The package contains two full sets of throttle balls and lever studs in four different sizes to accommodate a range of linkage geometries and installations. Having multiple sizes on hand helps ensure the correct fit without having to buy individual parts.

• Two complete assortments — ready for two carburetors or a spare set.
• Four distinct throttle ball sizes for varied linkage mouths and lever clearances.
• Lever studs included to replace worn mounting hardware when needed.
• Assortment reduces downtime during restoration or maintenance projects.

How durable and precise are the Joworthy throttle balls?

These throttle balls are manufactured from robust steel and finish-polished to improve contact geometry and reduce friction. The combination of material and machining delivers a balance of strength and smooth movement for long-term service in high-heat, high-vibration environments.

• Heat-resistant steel construction for lasting durability.
• Precision-machined ball heads and threads for secure fitment.
• Polished surfaces reduce wear on linkage components.
• Stable performance under frequent throttle actuation.

Will these parts fit my Holley 20-2 carburetor and replace worn components?

The kit is designed specifically to be compatible with the Holley 20-2 family, aiming to match OEM linkage dimensions and thread sizes used on those carburetors. They make straightforward replacements for worn or missing throttle balls and studs, especially during restorations or performance rebuilds.

• Engineered for Holley 20-2 compatibility — check fit against your existing parts.
• Ideal for replacing corroded or stripped throttle balls and studs.
• Helps restore precise throttle linkage geometry after disassembly.
• Includes extra sizes to address slight variations between vintage parts.

How easy is installation and what should I expect during fit-up?

Installation is typical of small carb linkage work: remove the old ball and stud, select the matching size from the kit, and thread in the new stud. Because the components are pre-polished and threaded, fit-up is usually smooth; however, minor adjustments to linkage position may be needed to eliminate any binding or end-play.

• Direct-thread replacement — install with common hand tools.
• Choose the best-sized ball for linkage clearance before final tightening.
• Polished surfaces reduce initial break-in friction during first runs.
• Package includes spare parts for quick swaps during adjustments.

Who is this for? Hobbyists restoring classic cars, mechanics performing carburetor service, and performance tuners who need reliable linkage components will benefit from this kit. If you work on Holley 20-2 carburetors or keep a parts stash for older vehicles, Joworthy's two-set assortment supplies the variety and durability needed to complete repairs quickly and get engines back on the road.
