    Why Buy A Carburetor From Us?

    Yes, you can certainly purchase a stock carb from the big mail order companies but we've seen carbs out of the box down on power as much as 40HP and between 15-20HP is common. That's why we disassemble and blueprint EVERY carburetor before we ever bolt it on your engine. We then tune, adjust and jet your carb on your engine so you get every once of power that you paid for.

    Even if you're considering one of our Sportsman Engine Kits or simply looking for a replacement carb, the same blueprint work is done and we dyno test it on a comparable engine to yours before it ships!
