This weekend i painted the original accelerator rod componentes which i received from Carl and today started to install them. I´m at the point of adjustment now and was wondering what the hard stop in idle is. I adjusted the carburator connecting link with the gauge pin installed, but as soon as i remove the gauge pin, the spring pulls the whole mechanism up a bit, while it goes through the overcenter position. Maybe the carburator connecting link must be bend somewhat, since i have the Edelbrock 1405 carburator? Or should there be a hard stop somewhere?

The gauge pin is named like this in the manual, its the rigging pin. At the moment I have it a little bit mis-rigged, the carburetor link a bit longer, so that the mechanism doesn´t turn through overcenter and the carburetor idle stop makes the hard stop for the whole mechanism.
Indeed I have the carburetor link installed like you havesigpicFrank

I have the stock linkage, when I got the car the transmission slipped, the linkage was way out and the carb didn't open fully.
Trial and error, use the settings in the manual as a starting point only, then its a 1/2 turn here and a 1/2 turn there until it's right.Scott

Thanks Scott. At least I know that the throttle plates open completely and that the overrun mechanism comes into action as soon as the mechanical stop of the carburetor is reached. (probably not the right name for the mechanism, maybe it even has to do with the kick-down of the transmission. At least the throttle plate movement stops and the transmission link continues to move)sigpicFrank

I had to lengthen my accel rod to work with the Holley I bought by straightening out the bends slightly. Mine has vacuum secondaries. Still tweaking the kickdown, float levels, etc months later. Was supposed to be factory set and "only needs slight adjustment" (ha). Carb is waaay undersized even though it is advertised as a 600 cfm. Feels more like 475 cfm.

Just finished the installation of the original accelerator linkage and man, what a difference that makes on the accelerator pedal. Before you needed to push very hard to get any movement of the pedal, and then the Bird was launched, now its smooth over the whole travel. Didn´t drive it yet to see how the transmission linkage adjustment is, but will do that soon.sigpicFrank
