Product Overview
 
Weber 48 IDA Idle Jets, 74823 are ORIGINAL Weber JETS FROM ITALY, we do not carry Chinese reproductions which do not flow properly! These are all genuine Weber jets which have been flow tested at the factory.
Item Features
We are aware that we are a little more expensive than other suppliers of Weber jets, but here is why you should use Aircooled.Net. First, we only sell genuine Weber jets from Italy! Secondly, we will tell you the correct jet sizes to minimize your jet expense, and your valuable time tuning! Other shops that aren't proficient at Weber Tuning will be happy to sell you jets at $4 ea, and you'll wind up with 6 sizes (24 jets) that you don't need! That makes no sense! By buying from us you will not spend more than you have to, our experience will keep your costs down, while providing the highest quality parts.

With that out of the way, we recommend the following idle jet sizes for sea level driving for dual IDAs.

55-60s. You can do further tuning with the idle air jets. With an IDA, the actual A/F mixture in the progression circuit is from the RATIO of the idle fuel and idle air jets. In the IDF and DCNF, the idle air is "fixed" via the air bleed, and that's why they have idle jets available in increments of "2.5". With the IDA you can change the idle air, so the idle fuel jets are only available in increments of "5". So if a 55/120 is too lean, you can try a 60/120. If that's too rich, try a 60/130. The bigger idle air leans out the mixture slightly. Being able to change the fuel and air jet lets you zero in on exactly what is needed.

Drop the size "1" for every 1k' rise above sea level. So if you have IDAs, in Denver (5k') you'd need ~50-55, but the same carbs at sea level would use 55-60.

Despite what you have read in "other" places, these sizes will result in the best running (cool) and stellar MPG. Use the main circuit for your power tuning! Read our tuning guide for further tuning tips, you'll save a fortune by buying the jets you need ONCE without guesswork!
