Weber Jetting Reference Chart:

Note that the 32/36 Series carbs have different size Main and Air Jets for Primary and secondary. The primary is the barrel that opens first when you move the throttle linkage. It is important to know both sizes and what barrel of the carb they are in. The 32/36 also has different idle jets and you need to know what style idle jets you have. See this link for the difference between them. Also refer to the exploded diagram for your carb if there are any questions about what part is what. Print out this form and write down the infomation for the jets that are in your carb(s). For DCOE, IDF, IDA, etc that does not have Primary and Secondary just use the blocks for the Primary jets. Be sure and include the "F" number for the idle jets on DCOE and IDA carbs. An Invaluable tool for learing all the basics and the technical side of these carbs is the Weber Factory Tuning manual listed at the bottom of this page...It is a great investment in your working knowledge of these carbs and will answer many questions about how they work.
