Pete;

You're most welcome.

I wouldn't call those "secrets", I'm just trying to help people learn what to look for before laying out $$$ for a carb.

Sometimes there's an issue with "unscrupulous" sellers/vendors (yes, there's more than a few out there), but sometimes neither the seller nor the (potential) buyer really know exactly what they're looking at. Honest mistakes happen.

Fact of the matter is this; none of this stuff is getting any less expensive any time soon, so the better informed people are (both sellers and buyers), the better off we all are.

Look for more pics later, I gotta get going.

Thanks for permission Eric, and thanks for the tips on printing. Actually I tried it in a Word doc, but the pictures didn't paste the first time and were way out of proportion and place the second time. Just tried it in Word Perfect and all pasted fine.

Thanks again.

Part 2:

Another issue common to both Holleys and Quadrajets are stripped fuel inlets. Holleys have the distinct advantage that repair is often as simple as replacing the float bowl. Unfortunately for QJets, it's a little more involved than that.

The fuel inlet boss on many QJets doesn't have much meat around it, which makes installing a thread insert an iffy proposition. When looking over a QJet for purchase, take the time to examine the fuel inlet threads to make sure they're not stripped, or on the verge of going as is the case here:

Next on the list is a re-visit to the topic of warped castings. The following pics clearly show how badly a QJet can warp; note the gap at the edges of the main body underneath the file:

Next up is a lovely QJet top casting with a serious case of the warps.

The pic says it all:

Last up today is a shot of the well plug locations mentioned in the first post. This just gives you an idea of where they are and why they can cause such a problem when they start leaking.

Great info. It is stuff like this that makes this site as good as it is.
