Overview:

Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle. QFX aluminum main body w/raised venturi Billet aluminum metering blocks with screw in restrictions Aluminum fuel bowls with dual sight windows and fuel inlets Nitrophyl® Floats (notched rear) and jet extensions Viton .130" Needles and Seats Billet Aluminum annular booster inserts QuickLink™ adjustable secondary opening adjustment Hand assembled and engine tested

    Sturdy, high-quality components
    Color: Vivid Orange1, Size: 16pcs
    Well-made reamer and plug inserter, as well as the 10 plugs, and the accessories. Even the pouch is high quality. Included instructions are very clear -- just be sure not to insert the plug with too much force, or you'll put the entire plug thru the hole. It's so much easier for a simple in-situ scooter tire puncture repair, where removing the tire can be much more time-consuming than removing a car tire. Including the high-quality little water/soap solution mister is a thoughtful feature. I highly recommend.

    The small set is convenient to carry.
    Color: Vivid Orange1, Size: 16pcs
    It works well and has a non-slip handle. Although there aren't many blades, it's enough for a family. The accessories are small but practical.

    Good for Beginners
    Color: Grey, Size: 16pcs
    Super easy to understand and very usable for a first time user like me. I did have to ask my friend to help me, but it was a super simple task with the instructions and good quality. Perks of working in construction lol, you get friends who know everything without needing instructions.
