It's the roundish part on the left with the rod sticking out of the bottom. This rod pushes down to hold the secondary closed. Vacuum above a diaphragm pulls it up and opens it. You will have to hold the throttle about 1/2 open to release the interlock (not shown) so you can move it by hand.

The solenoid does two things with a single action. It levers the starter gear out and makes contact and meshes with the ring gear on the flywheel, and physically connects the battery to the starter windings, like a huge switch.

 

Next time you are on the 'dead spot', place in neutral and use a remote starter switch directly connected to the starter solenoid. This eliminates a weak start signal from the ignition switch. Does this make it work????

 

 

No?

Next time you are on this 'dead spot', take the starter out and look at the starter ring on the flywheel. If it is not obviously damaged and the teeth look uniform, then I would say the solenoid is not connecting the battery to the starter winding. The loud click is the gear meshing with the flywheel, but you do not hear the starter turning.
