Q-750 - Quick Fuel Q-Series Carburetors

Performance & Value

Main Body

All aluminum (upgrade from existing designs)

Tumbled finish for a high luster that protects against contaminants

Recessed air bleeds out of air stream to improve airflow

Raised accelerator pump squirter nozzle boss also out of air stream to reduce the possibility of high-speed pullover or "dribbling"

Metering Blocks

CNC-machined from solid aluminum

4 stages of emulsion help break up solid fuel for leaner air/fuel sooner & excellent throttle response

Stainless steel idle mixture screw with a superior nylon seal that won't deteriorate over time like cork

Machined internal passages (vs. die-cast cored holes) ensure consistent performance and almost no chance of porosity holes cross-talking between passages

4-corner idle system for fine-tuning even with extremely long duration camshafts

Throttle Body

CNC-machined from solid aluminum for a more stable platform than die-cast equivalent

Teflon-coated throttle shafts with Teflon ribbon bearings reduce rotational resistance and nearly eliminate the use of the throttle body shaft hole as a bushing (great protection in dirt environments)

Mechanical secondary carbs have the Quick Link Secondary Opening System that enables rate adjustment simply by changing links (available opening rates: 40%, 60%, 1:1)

Mechanical secondary carbs also have adjustable secondary airflow cam brackets that allow better idle tuning with race-oriented camshaft profiles

Fuel Bowls

Die-cast aluminum for cooler fuel resulting in fewer fuel percolation problems

Sight glass to monitor fuel level without risking fuel spillage

All standard service replacement parts accepted

Floats based on application, i.e. Drag Race Carbs have notched floats & secondary jet extensions

Vacuum Secondary Carburetors

Exclusive billet secondary housing cover

Cover has an integrated screw that allows timing & opening rate adjustments with just a simple turn

Adjustable housing offers much finer tuning to dial-in application
