Signs the Four Horsemen of The Apocalypse are near:
Gas prices go over $5.
Pete Davidson gets to go to outer space.
Tom Brady comes out of retirement after just 40 days.
Charley buys this.

Charlie, I think you are very smart for buying that car. If I had the means and was offered it, I would have bought it in a heartbeat AND had the end carbs put back to work, propelling that beautiful car down the road.

It was actually just a spring to counter act the vacuum that was added to disable the end carbs. Simply unhooked it. Runs great. Pretty elaborate setup of vacuum lines for the carbs.

I thought they had block off plates under the end carbs and then figured out it was just the spring.

So the end carbs are actually controlled by vacuum ? I've never seen anything like that.

And apparently a really big vacuum tank.

Or maybe something is missing off this shaft coming out of the center carb.

----I know that in 1964 GTO's with tri-power the outside carbs were vacuum operated so it stands to reason that earlier Tri-power cars were also vacuum operated. Progressive linkage was out there in speed shops and guys rapidly yanked the vacuum system off. It was gone on my 64 GP and I never put vacuum back on as the car ran fine without it. I believe that Pontiac saw the light in 65 as 65 GTO's came with progressive linkage. California Chris could proably explain it better than me.....Bill S

My only experience was with an older cousins '65 GTO. He had the progressive rod rigged so when he street raced, he could lock it and the end carbs opened immediately. 4 speed with 4.11 gears and cheater slicks. Car was danged fast for the day.

Charlie,

I've done business with this fellow here......

His parts seem to be of high quality and he is a wealth of information.
