Early 1970's Carb Mileage Booster. Fun for the Garage Wall or Workshop

[Jolly_John]

Remember these from the oil crisis days of the early 1970's, Gang? Here's a new-in-box Tungsten Hydro-Catalyst carb attachment....just ready to boost your gas mileage by 27% (if you choose to believe the box!). Copyright date of 1973. It would make a nifty garage or workshop display item.
 

For a four-barrel carb. In never-used condition, with original box. Includes a photo and endorsement by none other than Mario Andretti. Carb bolt spacing 5-5/8" by 5-1/8".

Just $15, plus the actual cost of shipping. Your personal check or a money order are welcomed for payment. Thanks for looking. John

Well, if it's good enough for Mario Andretti...

Well, if one were to flip it upside-down and mount the screens so that they jam the secondary throttle plates shut, I can almost believe it might save gas...

 Never used! A Tungsten Hydro-Catalyst carb attachment is  terrible thing to waste.

Yes, that's true, Bernie. PLUS, I've just had an independent research laboratory do a metallurgical  analysis of this wonderful item. Their report (received here by certified mail this afternoon) indicates there is $86.37  worth of Tungsten Hydro-Catalyst (an extremely rare element) in this piece. However, being the good, non=mercenary person that I am, I WILL NOT raise the price of this item here on the forum. After all, "Fair is Fair"...I agreed to sell it to the guys here for only $15, and I'll stick by that price. John

Thanks for posting. I really enjoy looking at these marvelous gas saving devices; I used to collect them, but quit a few years ago. I actually found one that really worked. If I ever find it again, I will post a picture. Visualize a cardboard box approximately 4 inches square by 1 inch deep, with all of the "hype" about gas savings, government suppressed, oil company suppressed, etc. on the box. Open up the box, and there it is.........a boot heel

 

Another one is commonly available by the dozen at the local grocery. They come in both brown and white colors, for various driving conditions.

I remember those. Very humorous.

Is it just a rumor or did I hear the rare and valuable metals tax on Tungsten Hydro-Catalyst metal of $86.40 is due April first of every year, payable as a non-invoiced fee? Or did I get that mixed up with chlorinated fluorocarbons?

So many things to keep track of.
