The "plate underneath the air cleaner" is the air flow sensor. It deflects with increasing air flow, and thru a link, moves the metering plunger in the fuel distributor (FD). When you pushed the plate down during starting, you increased the fuel flow from the FD. After sitting for 11 years some of the small fuel passages in the FD may be partially blocked by dried fuel residue. Since you have another operating engine at hand, consider taking the complete air flow sensor/FD package from that engine and installing same on the current project engine. The reason? All known-good air/fuel metering parts remain together as a calibrated unit. While that is being done, you will be able to inspect all the idle air hoses and fittings, and the idle air valve for condition.
Re: fuel accumulator
The accumulator is located next to the fuel filter with a hard line on the pressure side, and a soft line on the leak side. To test for accumulator internal leakage, pinch off the soft line.
