Adjust Edelbrock Carb

Hi,
I own a 23 T with a 1970 Buick 350 fitted with a 795 Edelbrock Electric Choke Stock replacement carb #1904. Mt question is this:
I need to adjust the choke but it is encased with rivets and appears to have no way of getting at it. Does anyone know how to adjust this type of Electric Choke or even open the case?
Thanks from a Newbee.

Drill out the rivets (just remove the head,press out the rest) and replace with self tapping screws. All the carb overhaul kits I´ve bought for my Q-jet have them included.

Thanks Malc. I will check into drilling them from sort of overhaul kit. Then is it just turning the black cover as Meangrean suggests?
Also, does it take some sort of special drill bit or just a normal bit will do?
Thanks again

No need to go and buy a kit. Just take a 1/8" bit and drill just deep enough to pop the head off the rivet. Stop by most any hardware store and get some thread cutting screws/bolts that will fit the hole. Thread cutting screws are much prefered over sheetmetal type screws.

Take out the rivets, if you have to take the choke off, replace it with the tang in the choke housing engaged in the loop on the end of the spring.Rotate clockwise a tad and then counterclockwise until the rod actuating the choke flap just starts to move.Then by opening the throttle see if the choke closes,running the motor you should see it open, adjust from there as necessary.

I have the 1406 ... and here's the way to adjust:

1 - With engine fully warmed up, remove your air cleaner

2 - Loosen those screws you installed

3 - Turn the housing clockwise until the choke flaps START to close in the carb

4 - Turn COUNTER clockwise one knotch (1/8")

5 - Tighten her up.

#3, should´nt that be until the choke flap starts to close, not the butterflies?
