Well, as usuall, things progress.
914, 1972 with a 96x78mm four cylinder engine.
When I attach a fully charged battery to the car, turn on the ignition to start, very slow turning over of the engine. Leave the ignition switch in the on position and cross the 12V battery supply to the selinoid of the starter, the engine very slowly turns over. When I remove the screwdriver connection to the selinoid, the starter continues to turn the engine over for a few seconds, then quits turning over, or sometimes, I have to disconnect the battery. Hard to check a compression ratio. New rebuild on the engine (first time the engine is to be started). Compression ration calculated to be about 9.0:1.
Does this mean I will require a hi torque starter for this engine?
Thanks,
L. McC

I know it's hell to wait, but I can check our stock on Monday to see if we have a "good to go" used 911 starter.
I would have to charge $75 + freight from CA for it.

I can also see what they charge me for a rebuilt unit.

Oh, and from R&B Performance in Parker, AZ, I believe the owner Ron sells the "hi torque" (Nipponsenso gear reduction with a new nose) at swap meets for about $170.00.

Next thing to examine is the 12V lead from the battery to the starter. If that cable is old, it could have a very high resistance and be the problem. Voltage is not the measure, amps carried is.
