100 throttle linkage--help needed

Michael Oritt

Country flag
In order to remove the intake and exhaust manifolds to access to repair the broken exhaust pipe for cylinders 1 and 4 I had to undo the throttle linkage. Stupidly I did not diagram how everything was oriented prior to disassembly and I am having difficulty getting the linkage back together. Specifically, I need to know how the bell crank mounts:

1. Does its acute angle (less than 180 degrees) face up or down when the bellcrank is mounted on the post?
2. Is the spacer/bushing that is attached to the bellcrank facing inboard (towards the block) or outboard when the unit is slipped over the post?

Also, to what does the long throttle-return spring hook?

Thanks all for the illustrations and photos--once I saw the position of the bellcrank it all became clear and I was able to reassemble the throttle linkage this morning without too much difficulty. I do, however, have another challenge:

Before starting reassembly I decided to leave for last the copper drain pipes which mount to the underside of the intake manifolds. Now that I have everything bolted up I see that, because of the long inflexible drain pipes, getting the nipples started into the holes will not be an easy job.

That will be tomorrow's task....

This morning I attempted to install the drain pipes into the intake manifolds from under the car and though I could see the holes into which the nipples screwed there was no way I could make it happen.

So after having wasted an hour looking for an easy way out which did not exist I did what I should have done in the first place: I removed the intake manifolds with the carbs attached, pulled them about 4" from the engine and flipped them 90 degrees which gave me good access to the drain holes. Buttoning everything up did require some gentle bending of the copper drains as I repositioned the flanges but in the end it all went back together just fine.

Thanks all for the input.
