Re the block heater, yeah I am not wedded to that idea, just thinking over a few possibilities. That would achieve the one objective of not having the car sit there warming up and waking up the neighbourhood at 6am. Elsewhere it would not matter, pump it, start it, wait a few mins.
I had been planning to use a TQ that already had the choke removed, hence my line of thought.
Chokes work and can be made to work, I realise that, though remember they are only necessary because of the raw fuel that is dropping out when the engine is cold and going into your intake or cylinders, it's really a band aid - but does its job.
None of this is keeping me awake at night, either solution can me made to work!
