    you really need to do one change at a time to know for sure what happened.
    1 mm should not have changed rpm 300 to 400 rpm.

    now if your moved 3 mm then yes you can change 300 to 400 rpm.

    Does your ski flatten out or does it start to miss fire at high RPMs??IF it flattens out there is a good chance your to lean,IF it spits an sputters your to rich..Ive seen skis loose 3-400 RPMs do to a lean condition..The only REAL way your gonna know if your rich or lean is to put an A/F ratio guage on your ski..
