...100% Manually Controlled Radiator Fans...are Turned ON Only After the Engine Is Running. Also, Electric Fuel Pump is used to Prime the Float Bowls then turned off For Starting. Starter Cranks 'OK' But Not so Fast, High Torque Starter. Cold or Hot, Does Not Matter. I have a replacement Starter, must get around to Installing It. A Very HIGH Compression Engine! Don't Know if New Starter will 'ZING' the Engine to Life?
Last...The Battery is ALWAYS on a Tender! Starts and Leaves the Garage at 12.7-12.2 Volts. Cruizes at 13.7 Volts, 3100 RPM (Freeway)...I Have seen it at 14.2 Volts, with ALL Electricals ON.
The Starter cranking Slow...It's The HEAT!!...Higher Resistance! Carb Flooding RICH, has Nothing to do with Cranking SPEED, ONLY the actual Firing-Up and Starting, as in (Flooded and/or Vapor-Lock)!
FLOODED, as in the Carburetor.
'Vapor-Lock', is in the Fuel LINE, usually from being Too close to the Header. And Between the Fuel Tank and the Pump, Or Between the Pump and the Carb. Like an 'Embolism', it 'Locks' to Fuel from Flowing! In 'The Old Days', we use to Wrap a Soaking Wet Rag around the Fuel Line, this would condense the 'Vapor' and Un-Lock the Fuel to Flow.
