Starting Engine in Winter.

[Craig33]

Is it just me or is it more difficult to get the engine started when its 4° C outside. I seem to need heaps of throttle to get it started but it runs at its normal idle speed a few seconds after starting.

Redline with new carb, SwitchGlo, OS8 plug, Wildcat 30%

It's the temperature of the head and fuel mate. Which goes away once started. By lifting the throttle you are adding more of the stuff that makes it go bang. A bit like a choke in a car. Hope this helps

I did notice yesterday - zero degrees temp - that my little 7AH starter battery simply would not turn the starter over. Now that has to live in the house too to keep it warm.
Bloody cold it was - about 5 mins out in the flying area before back to the pits & warm coffee.
