What is this dohicky?

I just pulled my holley 2300 off my extra 292.
It has a large alumanum spacer underneth with an oval on the side sticking out about 2". There are a set of butterflies inside on a shaft that cannot be moved by finger pressure. On the rear of said spacer there are two 1/8" steel lines that were not attached to anything. The engine is from a 60 F550 grain truck. What is the dohicky for? Is it a second choke?

If I understand that right. This mystery set of butterflies is beneath the throttle butterflies and the intake.....

They governed it by limiting airflow? What if you need to increase throttle for a hard spot?

Prolly the same thing modern governed semis have to do today, start gearing down. I hated being governed.

Thats weird though, never heard of that.

Usualy a governer on a truck with a pto is to hold an RPM. Same with a truck following a combine. It is all about a steady speed.
