Weber DCOE 45 throttle linkage

What throttle linkage would you suggest for my 1981 GSL?
I have a stock throttle cable.

Not cheap, but a kit like this works very well with the wraparound manifold. Link
If I'm not misremembering, I think the stock cable sheath will thread into the frame.

my old setup before I went to the Lake Cities manifold:

You're not running a sidedraft carb on a stock intake manifold.

There are several different side draft manifolds around, but the important distinction is if it wraps around to put the carb over the engine, or if it's a straight "Lake Cities" type that puts the carb next to the engine over the exhaust.

I haven't seen a full Lake Cities setup, but the manifold I have has threaded mounting bosses on top that I used to mount a bellcrank setup that takes the throttle cable and operates the metering oil pump rod. The bellcrank sits in the exact position as the primary throttle shaft of the stock Nikki.



It's been a few years since I messed around with that, I should get around to finishing it My sticking point was trying to figure out what TPS signals the emissions computer is expecting, because I want to make the solenoid that controls vacuum advance to be functional. And I want to incorporate the evaporative emissions/crankcase ventilation system, because a functional evap system is crucial to prevent fuel from going stale when the car is parked six months out of the year.

Oh I see!
Its the wrap around type and sits over top of the engine then.
