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.
Eric
