Choke not attached, could that be the problem?

[Bigday]

My Volvo aq260 is stalling when I put it in gear, I have to gun the throttle to get it to go. I took the carburetor off and noticed the choke was not connected, could that be the problem?

The choke system on this carburetor uses a "Helix" (plus the linkage) to operate the choke plate.
The helix requires a heat source, of which may be electric, or it may use the exhaust cross-over in the intake manifold.
Please post a few pictures.

When cold, the helix contracts and moves the linkage and choke plate to the closed position, restricting air flow though the choke chimney.
This would be the normal position.
This restriction causes fuel enrichment for cold starting.

As the helix "heating element" (or cross-over) warms the helix, the helix moves the linkage and choke plate towards the open position.
Cold Start fuel enrichment begins to diminish.


Summary:
The helix in it's normal cold state closes the choke chimney off, making it cold start ready!
The heating element (or heat source) is what causes the helix to open the chimney up, backing off on the enrichment as the engine warms up.
The system should actually be called an "un-choke".


To adjust properly, this is done on a cold engine, making sure that the chimney is fully open once warmed up.
