Title: Crossover tube List 3793
Post by: dubsan on November 19, 2013, 04:33:47 PM
Does anyone know where I can find a crossover tube for  an OE Holly off 67 390 mustang/cougar  C70F9510-A  list 3793.  Am rebuilding carb but the existing line is faulty.
Thanks
Larry

They're available from most of the Mustang resto parts places. Both plain steel and stainless.
Here's a link to one:

Title: Re: Base Plate mixture screws? List 3793
Post by: Mike Caruso on November 28, 2013, 03:05:26 PM
Question on your carb.
 
Does it have mixture screws in the base plate on the primary's hidden by black epoxy in the front two legs of the base plate?

Turning them would adjust fuel to all four barrels which allowed a great idle with the big overlap camshaft.

It still used the ones in the primary metering block all you do is set them @ 1 1/2 turns out them install air cleaner. Run the engine or drive it get it hot and then open the hood and fine tune the base plate screws.

It came on my 1967 Fairlane GT 390 2.78 wide ratio 4sp and had the 304/324, .481"/.498" valve lift, 84 overlap camshaft purple stripe not the pink stripe 270/290, .481/490" valve lift, 46 overlap that cam in the automatic cars.

Just like carbs built with four corner idle screws but back in 67 and easy.

My brother sold his old wooden Chris-Craft 327 with my carb on it I wanted to smack him......Oh well.

* Update 02.06.2015 I think it was list 3793 date code 731 *
