One problem with quads off the shelf is that you cannot get high performance primary jets and secondary metering rods and/or hangers with them.

Rather than wading through one of my mispelled rants, use a search engine to find articles about jets and metering rods. If you see pictures of the various sizes of metering rods and different ptiches of hangers, it becomes clear. The only problem is that you cannot find the high performance jets, rods, and hangers.

(I saw a mix of metering rods and jets on eBay. Eveyrthing was there exept for the high performance ones. The price was through the roof. Imagine the buyer when s/he found out that these were the low performance ones that you could get for free out of trash carbs.)

This little known syndrome is probally the sole cause of the bad names of Quadrajets. I found the problem by pure luck, and I have never heard of anyone else finding the problem. If the "experts" are installing the jesus clip, and they are getting loading up complaints, this could be the cause. Before you give up on the quad, try this:

I had an intermittent loading up problem with my quad. I rebuilt it a bezillion times, along with a bezillion floats, all set at various levels.

On the last load up ever--around 1987--I took off the lid. When I touched the float, I noticed that the seat was sitting cadywampus, not sitting on its seat. The jesus clip--the wire clip that attaches the needle to the float--was making it bind. (I had replaced the jesus clip as many times as everything else.)

Because it's impossible for the needle to fall out, even if the car was upside down, I took the jesus clip out and tried the car. It has never loaded up since.

If anyone has a quad load up problem, I would strongly recommend that you remove the jesus clip. If someone could explain why the jesus clip is a nessessary part, I'd be more than willing to listen to their defense for keeping the part in service.
