Direct replacement for stock needle and seat. Provides much higher flow than stock. Unaffected by "G" forces like stock type needle and seats. Eliminates the need for special auxiliary float bowls for drag or road racing. Allows using extremely short float travel to cut down sensitivity in rough road conditions or hard cornering, yet flows more fuel than the stock type. Full flow in as little as 0.050" float travel. Practically eliminates the need for higher fuel pump pressures. Wide selection of sizes. Tip: Unless you have some extremely large size main jets you would normally select a size close to what you now have in the carb. After all, the needle and seat need not be much larger than one main jet. If you are running 190 main jets then the 2.1 or 2.5 is large enough. If you are running alcohol then you may need the largest size such as the 3.3. Comes with instructions on fuel pump setting for large sizes. |
