Holley linkage

[Chevyss]

I want to install secondary linkage to the Holley 4150. Any info would be appreciated. Is there a adjustable linkage. The last time I saw anything was a gear setup for the seconaries. Thanks in advance.

Royce, what kind of 4150 are you working on? double pumper or vacuum secondary? Are you trying to open the secondaries quicker?

 

Here is something that may help holley 20 122 I think that Summit gets $25 or so for it

Bob;

 

It's the carb that came with the 502. It has vacumn secondaries. All I want to do is to have the secondaries come on sooner. Manual linkage if you would.

change to a lighter spring in the vacuum pod on the carb. That will open it faster

Not sure if the carb you have Royce came with the quick change vacumn secondairs if not I would look into it, as it makes changing the spring easrier. You will work your way down on the springs until you find one that has a flat spot then go back up one. I've heard of people using the paper clip trick to open the secondairs faster.

Hey Guys, thanks for the information. I know we used to put a sheet metal screw in the linkage to get the secondaries to come on sooner.

If it a vacuum secondary USE THE SPRING KIT!
