You need a 110V 60Hz preheater. Use a stepdown from the UK supply.
Don't mess with other oils. Stick to the book. You can start them when new in an emergency but even then you gotta sit in 'em for 15 mins to get the temp up before thottle. Not rocket science.
When you sit in 'em during warm up NO THROTTLE.
Engine prime with the ignition off...please note...turn the prop 12 full turns....please note..if uncertain DO NOT DO THIS.
