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.

    WHAT I LEARNED
    Color: U.S.A, Size: Medium
    i AM NOT SURE THAT 4 STARS IS A FAIR SCORE, MY DOG IS AN AGGRESSIVE CHEWER, NEEDLESS TO SAY WITHIN 2 DAYS ALL THE TABS WERE OFF, BUT THERE WERE NUBS LEFT AND SHE CAN USE THAT. HERE IS A WHAT NOT TO DO, BRING IT TO THE DOG PARK, THEY ALL HAVE A BLAST BUT IF YOUR A BULLY/PIT MIX AND DECIDE TO SINK THEIR TEETH INTO IT, IT DOES DEFLAT. LESSONS LEARNED STILL A FUN TOY.

    Sturdy ball with pump
    Color: Black/White, Size: Medium
    Thick material so it won't pop so easy. Comes with a hand pump and 2 ball needles. Tabs for the dog to carry in his mouth. Although my dog bites the whole thing to carry. Savage loves it!

    The answer to calloused feet.
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
