STRUGLE TO START FROM COLD

[Tubz1983]

I use no choke on mine, haven't needed it yet. I just start it with a fraction of throttle if I need too, like literally a millimetre of turn, almost catching the engine as it fires off the starter, hold it there, and the revs rise by themselves within 5/10secs and I can let go and it warms up nicely.
