Street & Strip Carburetor Performance - Sweet Compromise

Summit's procedure for float adjustment is not new, but it's been effective for 50 years.

With the Summit carb, adjust the float level up or down and watch the sight glass. There's no need to unscrew a sight plug.

Summit uses center-pivot Holley floats and self-cleaning needle valves for reliable performance. The synthetic floats are ethanol resistant as well.

Blown power valves have always been a challenge with Holley and Autolite carburetors. Summit warranties its power valves for a million miles.

Vacuum-secondary Street & Strip carbs are fitted with a 30cc accelerator pump for just the right amount of fuel shot when the accelerator is pressed. With mechanical secondaries, a 30cc secondary accelerator pump is used for prompt power response when the pedal is mashed to the floor. Summit uses Holley accelerator pump cams. And if you must, you can step up to larger Holley accelerator pumps available from Summit.

Jet swaps happen without spilling fuel. Just remove the air horn and get after it. Because the floats are attached to the air horn, they don't get in the way. One challenge with air horn removal is that you must remove the choke assembly as well.

Booster venturis are traditional annular discharge types to spread the fuel mist evenly across each throttle bore. When the throttle is closed, fuel is metered via the idle circuit at the throttle plates.

Idle air/fuel adjustment is in the traditional location, yet angled at 30 degrees for easy access. Because this is a pure aluminum carburetor body, the adjustment screws are less likely to wander out of adjustment over time.
