Unless the engine is already running very lean the small amount of air normally admitted when you turn the EC on should not kill or affect the engine for more than a moment. It only admits the amount of air that is present in the power cylinder behind the diaphragm as the diaphragm pulls in to release the clutch.
Once the diaphragm is pulled in and the clutch is released, assuming the throttle is not touched and the car is not moving, no more than a tiny amount of air should be able to reach the engine -- far less than the windshield wipers -- unless there is a leak from a loose tube connection or crack in the power diaphragm that is continually admitting air. Once the throttle moves so the clutch starts to engage the valving blocks the vacuum supply and it is more a controlled bleeding off or admitting of outside air to that trapped vacuum contained in the power cylinder, not the use of more vacuum. The engine won't need to supply more vacuum until the clutch needs to release again. Does the clutch feel like the EC cable is adjusted and unit is completing and maintaining a full release? If EC is functioning and cable is adjusted properly, then assuming the proper 1 1/2" of free play is present in the clutch linkage the EC will pull the clutch in until pedal is almost to the floor. You can check by pressing on the pedal. It will be down almost to the floor or if it is one that stays up, it will require very light pressure until the pedal is 1/2 inch from the floor. The remaining 1/2" distance in either case requires normal pedal pressure to touch the floor

Hi All,
I found the problem!!! It appears that the new rubber diaphragm in the electromagnetic clutch actuator slipped out from in between the two metal discs. Strange symptom because when the engine is idling and when the electromatic clutch switch was pushed in the engine would simply quit. Kind of seemed like an ignition shorting out issue because there was no sputtering...just engine stopping as if the ignition switch was turned off. No strange noises or hissing sound...just shut down. To deduce whether the issue was electric or mechanical (vacuum) I revved the engine up to high idle and then when the clutch switch was pushed the engine would still run but at a much slower idle and sputtered a bit. So as to ensure nobody else falls for the same trick I did, make sure that the fused on washer is placed on the OUTSIDE of the two discs (not sandwiched in between). See attached PDF with pictures of what I am talking (typing) about. THANKS again for all of your suggestions.
