Product Description
Pair of idle pickup tubes with collars.
These would replace original tubes in Quadrajet main body in the idle circuit.
Select the size of the orifice you would like, or we will send as produced, which is about .035"
Idle tube sizes are not one size fits all for the restriction. There are many different restriction sizes from factory production. If you are unsure, please message us with your carb number and engine details. We can suggest a size and size them for you.
Larger orifice size produces richer idle mixture.
Our precision drill bits are perfect for sizing the tubes and other orifices in the Quadrajet.

idle down tubes
These corrected my rough idle from the increased cam size in my 74 Trans Am. I was idling at 15 to 1 A/F ratio with the factory tubes, and now at a much smoother idle at 12.5 to 1 a/f ratio. That carb was intially tuned for 100% gasoline, not our 90/10 mix we now are forced to run.

Necessarily need replacing when doing full rebuild.

Idle Tubes
These are beautifully machined, and correctly sized. If my engine does not idle correctly it won't be because of these!

New Idle Pickup Tubes
It's nice to be able to order your idle pickup tubes already drilled to the size you want and not having to fight with getting the collars pressed back into place without bending and damaging the tubes or the hassle of having to rob tubes from another core because you damaged one in the whole process. To be able to order these tubes just makes life so much easier.

Richen up that Idle ! To go with that new camshaft.
Use some 0-80 soft bendable stainless steel screws like these https://www.amazon.com/dp/B00IAVLJ4M?psc=1&ref=ppx_yo2ov_dt_b_product_details because they will screw right in the middle of your old Idle jets and you will be able to lever them right out ! Then just drill the new Idle jets (pickup tubes) to the size to compliment your set up ! These fit perfect ! Thanks Charlie

Just arrived today (June 27). Glad to see that your tubes are two piece to allow future removal, if ever. Just did a couple of marine apps that had single piece units. Main tube ID was 0.042 (w/0.039 res) compared to OE ~0.052. Boat had to move so I drilled upper ID to 0.048 by hand and hopefully it reduces the fuel drag. Thanks for product.
