Carburetor Jet Kit

(High Elevation)

This kit is used to make the air/fuel mixture leaner. A properly jetted carburetor, that worked well a couple of years ago, may have lost some of its performance due to today's leaner fuels. Some symptoms of a lean fuel condition are: needing to adjust the idle too high, rough idle, hesitation or stumble on acceleration, a flat spot at around 2500 RPM and/or surging at a constant RPM in higher gears.

Along with leaner fuels, any modifications to an engine to improve performance can compound the lean effect and require more mixed fuel volume. Modifications could be as simple as an opened or larger air filter, an open exhaust system, or ignition modifications. Some modifications could be as extensive as a larger camshaft, head modifications, headers, or increased engine displacement. Also, altitude & extreme temperature or humidity affects the air to fuel ratio. Any and all of these modifications are exaggerated when combined with the lean fuel.

Weber recognizes your need to have a variety of jets for all circuits available when tuning your engine. These jet kits come with simple tuning instructions and a variety of jets to cover the stock and modified engine and are designed using years of experience jetting carburetors on engines all over the country with all types of modifications. If you are experiencing any of these symptoms from your Weber carburetor or simply want to improve the quality and performance from your engine, these kits are for you.

These jet kits contain mains and air jet ranges developed around traditional calibrations, based on Venturi and engine displacements. Kits should provide a range of calibration flexibility to help tune most applications.

Kit Includes (2) of each:

  • Main Jet 135 , 140, 145
  • Air Correction Jet 190, 200, 210
  • Primary Idle Jet 40, 45, 50
  • Secondary Idle Jet 40, 45, 50

NOTE: Not for 32/36 series carburetors. Jets and kits are non-returnable items! In order to richen your air/fuel ratio you will need jet kit, see Part #: 1035006.

Reviewer: Johnny De'Scoville from Taos, NM United States  
Just what these 22Rs need up here in the mountains of Northern NM.
The Weber 38 works great all around -low end ,mid range and open throttle but the high elevation kit boost it up in a big way. I run the same setup on my 83&85 Yota 4x4 PUs
Thanks LC !!!
