Went to Decatur today and Mark Bullard Modified my carbs for my twin DD 67 CARBS

PEEK Barrels

REDUCED size of the carbs

New throttle arms

MAJOR IMPROVEMENTS

CALL MARK and get your carbs done. 1-256-303-6423

BTW the plugs in the carbs is how one gets the carbs the same when settling up the throttles

The last photo shows how the bottom of the body of the carb is turned down so the carb sets lower on the opening so that it engages the O ring at the bottom and thus helps to keep the carb in place.

so doc, your saying that the bore of the venturi is bigger than the bore of the barrel?? if so,what are both the measurements? PS,you have way too much time on your hands since you retired..it's not fair....

Bore .470 for 67’s

Mark Bullard did the mods

He has done several dd carbs

We put peek barrels in all of our carbs, CMB ETC
 
.470 just under 12mm that is a good size bore dia.

My Nova .67DD has a KRE 12.5mm ready when i rebuild..Though 12mm may be better on the hot weather..

I was running the dd91 carbs when I ran 85 mph.

So these are obviously smaller for heat racing on a small BRANDON POND

BTW SEE THE DIFFERENCE IN THE CARBS
 
yes, I think .470ID is a perfect size intake for a .67 displacement.

I have a PEEK wedge section fused between two vertebrae on the anterior, or front side, of my sacrum spine (S1 and S2). This is to provide stability for the fused rear, or posterior side, spine. I have every vertebrae fused, from nearly top-to-bottom. Only C7 and above are not fused. Fun
