Overview:

In circle track classes that mandate two-barrel carburetors, customizing a street carburetor has been the norm for decades. Not anymore. Designed from the ground up to meet the unique demands of circle track racing, QFT's new XP-Series offers the performance benefits of a custom carburetor in an affordable, turnkey, class-legal package. At a bare minimum, modifying a standard street carburetor for circle track duty typically involves changing the throttle-plates, floats, and metering blocks. These custom modifications can easily exceed the cost of a turnkey QFT two-barrel carb while still lacking many of the key features that only a clean-sheet redesign can offer. A high-flow aluminum main body design centers the venturi over the throttle-body assembly. To further increase airflow, QFT centers the air horn over the venturi, removes the choke tower, and carefully profiles the air inlet transition. The result is enhanced airflow and fuel distribution, which improves throttle-response and horsepower. All XP-Series carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life. Available in 500- and 600 cfm sizes, the XP-Series sets a new standard in two-barrel circle track carbs. High-flow aluminum main body with centered venturi for improved performance and better air/fuel distribution Black anodized billet 2-Circuit metering block and throttle body Throttle body incorporates roller bearing seals which provide smoother operation, less wear on shaft, and longer life Anti-siphon check valve in main body to reduce pump pull-over Changeable emulsion bleeds and power valve channel restrictions for better tuning capabilities Dual inlet fuel bowl with #8AN fittings Dual sight glass windows for easy float adjustment Single wedge circle track float Exclusive Black Diamond® coating for enhanced corrosion protection and appearance. Provides a 6% reduction in fuel temperature.

    Smells of smoke
    The plastic smells of tobacco smoke, my puppy took one stiff and walked away. I wash them with soap trying to get the smell to go away, no change. My dog still would not even try to teethe on this. I do not recommend.

    Wonderful teething toys for small teeth!
    We bought these for our new three chihuahua babes and they love them so much! For now, since the babies still get really cold, we just do them as is and are going to hold off on freezing them for a bit but it's still great! They love to chew on either end and the different textures of both the rag and the different ones on the bone itself, keep them really entertained.

    Gumby is a hit!
    Size: 9 inches - Plush Gumby, Size: 9 inches - Plush Gumby
    The dogs LOVE their Gumby toys! Do I expect them to last long? Not with this dog. In fact, the dog pictured began chewing Gumby's arm off shortly after this photo and had to be redirected, given a chew, and the Amazon box to shred before trying Gumby again. However, if your dog is like my Boston and more gentle on soft toys then this toy will last a long time. Her Gumby remains fully intact and loved. So, if you're buying this, just know your dog's style of play and how they treat soft toys, then purchase with reasonable expectations. I knew my wild man would destroy this, he destroys the tough made stuffies, but he has fun doing it and you can't beat the $3 price. Overall it's a cute toy at a good price. It's fun to play fetch with it in the house, but I wouldn't tug at it. Playing tug could rip it.
