Removing the power jets from a Holley 2280 can be tricky because they’re often recessed, can seize from varnish or corrosion, and are easily damaged if you use the wrong tool. Here’s how I’d approach it:
1. Make Sure You Have the Right Tool
-
Proper screwdriver – The slot in a Holley power jet is narrow and deep. Use a hollow-ground screwdriver bit that matches the width and fills the slot completely. A tapered hardware-store screwdriver will cam out and chew the slot.
-
Long shank or bit extension – On the 2280, the jets are down inside the main body, so you need reach.
2. Soak to Loosen Deposits
-
Spray carburetor cleaner directly into the jet area and let it sit for 15–20 minutes.
-
For stubborn cases, use penetrating oil (like Kroil or PB Blaster) and let it soak overnight.
-
If the carb is apart, submerge just the main body in carb dip for a few hours.
3. Break the Grip Without Damage
-
Seat the screwdriver fully in the slot.
-
Apply firm downward pressure while slowly turning counterclockwise.
-
If it’s stuck, lightly tap the screwdriver handle with a small hammer while maintaining torque — the shock can break varnish bonds.
4. Heat for Stubborn Jets
-
A small pencil torch or controlled heat gun blast on the carb body around the jet can expand the aluminum slightly, freeing the brass jet. Don’t overheat — keep it under 250°F to avoid warping.
5. Last Resort: Impact Driver
-
A hand impact driver with a proper bit can give controlled rotational shock without stripping.
-
Use only if the carb body is firmly supported and you can keep the driver perfectly aligned.
Pro Tip: When reinstalling, use a dab of anti-seize on the jet threads and never over-tighten — snug plus a tiny bit more is all you need.
