Edelbrock 1406 whistling

I've never in my life seen seals on a carburetor throttle shaft. They are always just a tight fit through the carburetor base. Now I've worked on and tuned some Edelbrocks, but I've never torn one all the way down so they might have an o ring there, I don't know. The usual fix there is to have the throttle base plate drilled out and bronze bushings installed. Before I did anything, I would check the warranty on it from where you purchased it from. It could be that it has a one year warranty. Some things do.

Also.....on the carburetor cleaner thing. I recommended water in a bottle because a friend in high school auto shop class was using carburetor cleaner to hunt down a vacuum leak. He sprayed too much in and whether the engine ignited it or some got into the distributor was unclear, but it flashed back into the engine compartment and burned him severely. I remember it well because some of our shop class had to hold him down while he was trying to peel the freshly burned skin off his face. The resulting fire also burned the entire under hood area of the car before the shop teacher and I could run get fire extinguishers and put it out. So some people may ask "SO WHAT"? There is your "SO WHAT". My thing has always been why in the world risk being hurt when water will work just as good? It just makes no sense. THAT'S WHAT.
