Edelbrock 1406 whistling

No throttle shaft seals on Edelbrock carbs.

I just found that out. :!:

So, after dissecting the spare carb, and making that discovery, I went back to square one and decided to try to diagnose the new carb. I swapped the (working) 1406 off of my '62 Ford 302, put it on the 318, cranked it up, and was surprised to discover IT DOES THE SAME DAMN THING. Whistles like a mother. I sprayed this carb at the base, and I definitely got an increased idle....I sprayed it at the secondary shaft, and it didn't change at all. Sunofabitch. :banghead:

Sooooo....I've decided to take Stroker and Hornet's advice, and replace the gasket...again. It's got a new one on it, but the parts guy had an issue finding it, so I wonder now if it's the correct one (the thick Felpro version). They have a Mr. Gasket spread bore type, so I'll try that one next. I really can't believe the shaft would be leaking....it just doesn't seem logical.

I'll let you know.
