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.

    Looks great.
    Love the look. Took a bit to put it together. The only negative was putting on the back with the tack nails. There was no way to see if you were hitting the board so I missed it about 1/3 of the time. Might be better to use wood glue and forget using the nails.

    Perfect for a small bathroom
    Nice cabinet for the bathroom. I have a 120-year-old house with small bathrooms; this doubled the cabinet space; the white keeps the room visually larger. I'd like to add the instructions are awesome: no verbiage just step by step diagrams. Each hole drilled and ready, as well as pilot hole where the screws will be received. Each piece labeled. The instructions have in the listings the count of pieces with a notation of extra screws, so you don't think you "screwed up" when you're done. One note: as the shelves are part of the construction, they are not adjustable, in my case not a big deal.

    Decent product, you get what you pay for
    Easy to put together and good price, fit the space we had perfectly. Cheap material, but you shouldn't be surprised considering the price. I saw another review commenting on the difficulty lining up the nails for the back. Wish I would have read it before the assembly as the nails popped through the front side and I had to knock them back and repaint the spots. The directions don't state which size drill bit to use for the wall anchors, but 5/16" worked well. Overall, not great but not terrible either.
