Carb spacer throttle linkage woes..

[Yellow75]

Installed the carb spacer because after I let it sit the fuel would boil and it was always hard to start. Now the angle is wonky and it's pretty hard to lightly give it gas the break over angle is too steep or something. I've tried different springs etc but can't figure it out. Anyone have any tips? I have to be missing something that is going to be completely obvious.. Pressing lightly on the throttle does nothing then once the resistance clears it lunges and goes at least 20% throttle.. No easing into it. Edelbrock 650

Is there any way to re-clock the throttle arm so it's closer to 12 o'clock when the throttle is closed? My motorcraft 2bbl sits at about 11 o'clock. If you can't do that, I can recommend this https://www.wildhorses4x4.com/produ...arrel-Throttle-Cable/bronco_More_Engine_Parts. It says 2bbl, but works for both. Mine issn't on the road yet, but sitting in the shop the engine accelerates smoothly, and it's easy to install. Has three height selections, I'm using the middle one for the 2bbl with spacer., so you can go one step higher. Just realized I let my contributor status expire. I'll post a pic when I get that fixed!

On the firewall bracket with the bent arm on the driver side, and fairly straight on pass side, mine doesn't look as strait, or didn't, it had the passenger side arm bent toward driver side, most likely to clear downshift rod.

Does the throttle hit the floor at wide open?
If so, the distance from throttle shaft center to the linkage pivot would be the correct length. Then just a matter of making a way to clock that pivot point so midpoint of the throw is at the 12:00 position of the carb lever.

Does it still do this with the kick-down lever disconnected? The problem may be there and not in the linkage itself.

Suggest re-positioning the throttle return springs. They're nice and clean looking in that location, but it wears out the carb's throttle shaft bores faster than if they are placed to be directly opposite of the linkage's pull-rod.
