Hi

I just made break in for my 1.60 gasser. I didnt fiddle with needles(manual said so) and the temperature was -12 degrees celsius. I runned 500ml of 1:30 fuel with recommended oil(Mobil 2t racing synth). Engine is starting fine, but I cant get it to running with full throttle. It just starts to die out after 1/2-throttle. What are the basic break-in needle settings? I just dont want ruin my engine running too lean so I want to check safe break in needle settings.
