Overview:

While modifying a street carburetor for circle track applications can work reasonably well, Quick Fuel Technology's Q-Series circle track carbs eliminates the guesswork and offer substantial advantages in adjustability, consistency, and predictability. Since racing around a banked oval pushes fuel to the passenger side of the car, Q-Series circle track carburetors feature die-cast aluminum fuel bowls with internal baffles that eliminate slosh. The bowls also feature an integrated fuel chute that substantially reduces aeration, and directs fuel toward the main jet pickup area. To assist in flattening out the fuel curve, screw-in air bleeds enable fine-tuning of both the low- and high-speed systems, while a proprietary booster design enhances carb signal without restricting high-rpm airflow. Helping drivers put the power down is an adjustable QuickLink system that allows changing the opening rate of the secondaries to 40-, 60-, or 100 percent. Circle track Q-Series carbs are available in 6 different sizes ranging from 650-1,050 cfm for both gasoline and alcohol applications. All Q-Series circle track carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life.

    Great value and chair!
    Color: Fabric-grey, Size: Luxurious(With Wheels)
    Great chair and value! I got this to use with my work desk. It’s not super padded and I don’t know how long it will last, but it’s comfortable and the height is adjustable. It feels solid and my teenager was able to put it together with the instructions. It looks nicer with my desk than I thought it would. The fact I can sit “cross cross apple sauce” was the most important feature!

    Comfortable, Stylish, and So Easy to Assemble!
    Color: Leather-beige, Size: Luxurious(With Wheels)
    I recently purchased this chair and honestly, I’m very impressed! It took me longer to unpack everything than it did to actually assemble it. The setup was quick, simple, and the video instructions on YouTube made it even easier. The chair is super comfortable, rolls smoothly, and fits perfectly underneath my vanity without taking up too much space. I know it’s marketed as a “cross-legged” chair for younger users, but at 57 years old, sitting cross-legged isn’t exactly happening for me anymore 😂 — and I still absolutely love it. It’s stylish, comfortable, sturdy, and perfect for everyday use. I would definitely buy this chair again and highly recommend it to anyone looking for a cute and functional vanity or office chair!
