70 l78...
The photo you show with the throttle spring is helpful...the small one with the bracket is the factory setup...the other larger spring was never part of the equation.

Great! I can handle removing a spring.
But, regarding the comment... "I see a vacuum hose connected to a port near the air-horn on the carburetor...can't quite see where it goes, but it looks like it is running to the distributor vacuum advance ?? If so, this will not give you the correct vacuum source for the advance" It would be helpful if I could get more clarification. In my previous post there was a photo that appeared to show the distributor vacuum ultimately (after the TCS solenoid) connected to that air horn port. For reference here's my older post. https://www.yenko.net/forum/showthread.php?p=1302936 Anyone else with this carburetor and no TCS solenoid out there? Thanks

No TCS..
You want manifold vacuum to the distributor....just tee into the line by the choke pull off and you will get full vacuum. The factory had these set at 4* btdc...if you have good fuel this can be kicked up. I run a total of 36* all in by 3,000 rpm. You can play around with the initial and then adjust the mechanical weights to get you to the right spot. A dial back lite is handy for this.
**TCS can be installed just for looks and made inop...these motors like a little lead on the crank, especially if you have the other aspects dialed in...carb, fuel, gears, plugs, etc.

O.K. I will tee it in, and... I'll stop stressing about that other carb port.
*** Thanks *** Don And done... white line hose is distributor vacuum advance which I ran along the passenger side valve cover using the pre-existing TCS clips. Last edited by Diamond_Don; 09-10-2017 at 12:29 AM.
