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 assume the starter is not new.
It may be the contact inside the solenoid being corroded and sticking that cause it to run afterward. Solenoid is no good. Plus, the starter could be just worn out. At 9:1, it shouldn't be a great problem. Get the 1.2? 1.8 kW 911 starter (SR68X) instead of the 914 0.8 kW starter (SR17X) - it will spin readily if all other things are in order. |
