If your Harley has an S&S Super E, order the Master Rebuild Kit 11-2923. If it has a Super G, order the Master Rebuild Kit 11-2924. Choose the Master kit when the carb has been sitting, leaks fuel, or has an unknown history. Choose the Basic Rebuild Kit 110-0067 when the carb is low mileage, and you're only refreshing seals after a cleaning. If the only problem is a stumble when you whack the throttle, the Accelerator Pump Rebuild Kit may be all you need.
The Super E and Super G share a lot of internals, so a few of S&S's kits fit both carbs, while the Master kits are carb-specific. This guide shows what's in each kit, which symptoms point to which part, and what to check before you order.

Which Kit Do You Need? Start With Your Symptoms
|
What your carb is doing |
Likely culprit |
Start with |
|
Sat for a season or longer, smells like varnish |
Dried gaskets, gummed passages |

Floods, drips from the overflow, or won't stop leaking fuel |
Needle and seat, float level, bowl gasket |
Master kit |
|
Bog or stumble when you snap the throttle open |
Accelerator pump diaphragm or check ball |
Accelerator Pump Rebuild Kit |
|
Rough idle you can't tune out |
Idle mixture screw, seat, or an air leak |
Master kit |
|
Fuel seeping at the bowl or manifold |
Bowl gasket or insulator O-ring |
Basic kit or Master kit |
|
Low-mileage carb, already cleaned, just needs fresh seals |
Aging gaskets and O-rings |
Basic kit |
|
Throttle feels sticky or loose |
Throttle shaft, return spring, or seals |
Master kit |
These are common patterns, not a diagnosis. Dirty jets, vacuum leaks, or ignition problems can cause the same symptoms, so clean the carb and check the basics first.
S&S Super E vs Super G: What's the Difference?
Both are S&S's popular carburetors for Harleys and custom builds, with an adjustable accelerator pump, an O-ring sealed idle mixture screw, and a design that needs a two-cable, pull-open and pull-close throttle. The Super E uses a 1-7/8 inch bore, and S&S lists it for engines up to 100 cubic inches. The Super G is the larger carb, built for bigger-displacement and higher-flow setups, so check S&S's tuning chart for its bore and application.
What matters for rebuilding:
- Master kits are carb-specific. The Super E uses 11-2923, and the Super G uses 11-2924.
- Some parts are shared. The Basic Rebuild Kit (110-0067) and the Accelerator Pump Rebuild Kit are made for both Super E and Super G carbs.
- Shorty carbs count as Super E. Retailers confirm the Super E kit fits Shorty Super E bodies.

S&S describes the Basic kit as a gasket and seal kit for low-mileage Super E and G carbs, and a good way to reassemble a carb you took apart for cleaning. Retailer descriptions of its contents vary, so confirm the parts list on the listing before you rely on it for a major repair.
What Comes in the S&S Super E Master Rebuild Kit?
S&S lists the Master kit as including a body rebuild kit, all new fasteners, springs, an idle mixture screw, a seat, and a needle assembly. Retailer descriptions add the accelerator pump parts, a bowl gasket, an insulator block O-ring, and the blue O-rings and check balls that riders often forget. Three notes:
- Jets and the float aren't included. Plan to inspect and clean or replace them separately.
- 360-degree fuel inlet: if you use the variable position gas inlet, S&S says a fuel line with a 90-degree formed end must be ordered separately.
- Fuel type: retailer notes say the kit isn't intended for racing or alcohol fuels.
What's in the Body and Accelerator Pump Kits?
- Body rebuild kit (part of the Master kit): throttle plate, bellows seal, throttle shaft nuts, pump actuator spring, throttle return spring, throttle shaft, bowl gasket, O-rings, plastic shell, hardware, and instructions.
- Accelerator Pump Rebuild Kit (11-2918): diaphragm, diaphragm spring, check balls, check ball spring, pump pushrod, hardware, and O-rings. It fits Super E and G carbs.
Accelerator Pump Rebuild Kit: The Fix for Hesitation
The accelerator pump gives the engine a squirt of fuel when you open the throttle fast. A stiff or cracked diaphragm, a leaking check ball, or a tired spring can cause the hesitation riders call a bog. If that's your only symptom and the carb is otherwise clean, the pump kit costs far less than a Master kit and covers exactly those parts.
S&S also sells diaphragm springs in multi-packs. They matter if you're tuning pump response, so check the listing for the spring details before you buy.
Other Parts You May Need
- Two-cable throttle: Super E and G carbs need a pull-open, pull-close throttle assembly. Browse throttle and clutch assemblies and cables.
- Gaskets and seals: see the gaskets and seals category for intake and manifold sealing parts.
- Fuel filter and air filter: fuel filters and air filters protect your fresh rebuild.
- Carb cleaner: pick up cleaners for jets and passages.
- Replacement carb: if the body is damaged or worn beyond rebuilding, an S&S Super E carb is the next step. Browse the carburetor parts category.
How to Rebuild an S&S Super E or G: A Quick Overview
This isn't a full manual, and S&S's own instructions and tuning guide should lead the way. Here's the rough sequence riders follow:
- Photograph and label everything as you disassemble the carb.
- Clean the parts and blow out the passages. Don't poke jets with wire.
- Replace the wear items in your kit, including the needle and seat, gaskets, O-rings, and diaphragm parts.
- Check the float for leaks or sticking and set the level per S&S's instructions.
- Reassemble and install, checking for air leaks at the manifold.
- Set the idle mixture and tune as described in S&S's tuning guide, then road test.
Jetting After a Rebuild
A rebuild restores the carb to its original condition. It doesn't re-jet it. If you changed the air cleaner, exhaust, or engine since the last time it ran well, plan to check your jetting. The Master kits don't include jets, so jet kits are a separate purchase. S&S publishes a Super E and G quick tuning guide with a disassembly and tuning video. Read plugs after a test ride and adjust one change at a time.
How Often Should You Rebuild an S&S Carb?
There's no fixed interval. S&S carbs hold up well, and retailers describe the Super E as nearly infinitely rebuildable. What matters is use and storage:
- Inspect it at the start of every riding season and after any long sit.
- Rebuild when you see symptoms, such as leaks, flooding, hesitation, or a rough idle that won't tune out.
- Rebuild if the history is unknown, like a bike you just bought or one that sat for years.
Ethanol blends and long storage are hard on rubber parts, so fuel stabilizer and draining the bowl before storage help. For deals on shop supplies and parts, see our guide to saving on brand-name powersports gear.
Before You Order: A Quick Checklist
- Confirm Super E or Super G.
- Decide Master, Basic, or Accelerator Pump based on your symptoms.
- Check for the 360-degree inlet, and order the S&S fuel line if you use it.
- Plan for the float, jets, and cleaning supplies, which the Master kit doesn't include.
- Check the listing contents, because retailer descriptions differ.
Frequently Asked Questions
What comes in the S&S Super E Master Rebuild Kit?
It includes a body rebuild kit, all new fasteners, springs, an idle mixture screw, a seat, and a needle assembly, and retailer descriptions add accelerator pump parts, a bowl gasket, and the blue O-rings and check balls. It doesn't include jets or the float.
What's the difference between the Super E and Super G?
The Super G is the larger carb, aimed at bigger and higher-flow engines. The Super E uses a 1-7/8 inch bore and is listed for engines up to 100 cubic inches. Their Master rebuild kits are carb-specific, and some kits fit both.
Can one rebuild kit fit both the Super E and Super G?
The Basic Rebuild Kit (110-0067) and the Accelerator Pump Rebuild Kit are made for both. The Master kits are separate: 11-2923 for the Super E and 11-2924 for the Super G.
How often should I rebuild my S&S carb?
There's no set mileage. Inspect it each season and after storage, and rebuild when it leaks, floods, hesitates, or won't tune.
Do I need to re-jet after a rebuild?
If nothing else changed. If you modified the air cleaner, exhaust, or engine, check your jetting.
Is the Basic kit enough?
For a low-mileage carb that's been cleaned and needs fresh seals, yes. For a carb that sat, leaks, or has an unknown history, choose the Master kit.
