Engine barely turns over, need help Options

[solex]

I have done a lot of work and had the car running fine for serveral but now I have an electrical problem that I cannot seem to find.

Symptoms:
Starter will turn a few degrees but will not turn over the engine when I release the key the starter will turn over a few more degrees as though I still have the key in the start position.

What I checked:

1. Battery was tested and showing 12.58 volts
2. Checked current draw looking for a dead short on negative side of battery (no current draw indicated)
3. Also had a charger (in start mode) hooked up while starting
4. The starter was rebuilt and a new solenoid was installed the starter was bench tested
5. The starter relay was also removed and bench tested
6. Visual inspection of the wiring in the engine bay and underneath the car, I could not see anything obvious

Recent work done (may not be relevant):

1. Installed 123 D-Jet distributor (using curve D)
2. Rebuild Fuel Injectors (Mr. Injector)
3. Adjusted Fuel Pressure was 26 psi is now set at 28 psi
4. New cap, rotor and wires
5. New spark plugs W7C W175T2
6. All new vacuum lines
7. Compression checked #1:145 psi, #2:135 psi, #3:145 psi and #4:145 psi
8. Replaced activated charcoal in charcoal canister (no more gas smell)
