The accelerator pump jet is a vital component of the carburetor's accelerator pump system. Its primary function is to instantly squirt an extra, precisely metered amount of fuel directly down the carburetor throat the moment you open the throttle quickly. This compensates for the sudden rush of air and prevents the engine from hesitating before the main jets have time to initiate sufficient fuel flow.
Selecting the correct size for the accelerator pump jet is absolutely crucial for achieving a clean, crisp, and immediate throttle response. If the jet is too small, the engine will hesitate or stumble upon acceleration (running momentarily lean); if it is too large, the engine may receive too much fuel and bog down.
Compatible with the following carburetors (among others):
- Weber 40 IDF
- Weber 44 IDF
- Weber 48 IDF
Please select your desired size from the drop-down menu above before adding the item to your cart. Keep in mind that the jets are sold individually and a standard IDF carburetor requires two jets (one per barrel).
