I'd employ an ex-Flight Engineer to have my Druine Turbulent outside the hangar, pre-flight check complete ( I'd always trust a F/Eng.) started, and engine warm enough when I turned up, so that I could just jump in, wave the chocks away and tell him I'd be back in an hour, go make yourself a cup of coffee.
By the time I've got the bugger started I've lost most of the enthusiasm.
Bliss, and there is a possible candidate available - all I need is the $200 m. NZ $, his present rates are too high - beer isn't cheap.
