This carburetor kit has a GX390 carb with a special adapter and fixed jet. It includes all gaskets, bolts, filter adapter, jet, and an air filter. The special design eliminates the insulator. The carb is mounted at 15 degrees for karts using 15 degree mounts.

*Note: Bored carbs are only recommended for big bores and extreme RPM engines. Under most circumstances, a stock bore carb will perform better. Prices for some kits are slightly higher than shown; please verify price in cart.
