I have a new MVVS 58 and would like some help -

I have put about 4 litres of fuel through - at 30:1,
After practically every run I have had to richen the bottom and top (maybe 1/8 turn)

Is this normal ?

When will it be "RUN IN" ?

Please also confirm - If the motor starts BACKWARDS - it is a sign of being lean at the bottom end

Best regards
Dominic Stevens
