4150 throttle linkage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone running a 4150 Holley? What are you running for a throttle linkage? Cant seem to get the secondaries to open with the stock cable.

You can get a 4150 in both vacuum and double pumper, also most are DP's. If you disconnect the linkage, can you get them to open up by using your hand? Think we need a little more info. You can get them to open up just fine with the rod style or cable. I am using both. Must be a geometry issue. Pics of what you are currently trying would help so we can see where you have it hooked to the carb.

Of course;
Its a mechanical secondary 925 blow through application from the Carb Shop. Yes, I can open it by hand. Im hoping to use the stock cable, and pedal as I hope you can see in the pics. Im using a Jegs adjustable bracket, but Im thinking maybe the stock bracket would be a better choice?
Anyway, the way it is now, it ony goes far enough to open the primaries. My Cobra buddy says, "Hey, thats a great govenor!"

Sorry, the last pic is fuzzy...
TIA, Tom

I would say you need to move your ballstud forward to the hole in front of where it is now.

Ball stud needs to be where return spring bracket is now.
