    2000 XP Correct Carb Setting for R&D Arrestor

    Have a 2000 XP i just bought. I had some electrical problems that I have now sorted.
    The motor is fitted with an R&D air plenum.
    I have checked the carb sterings and they are as follows, acc pump is still fitted.
    Ski will be used at sea level.

    Lows 95 on both
    Highs 147.5 and 145.
    N+S 2.3

    Can anyone confirm if these settings are correct. I have never modified carbs before for aftermarket arrestors.
    Thanks in advance

    Thanks in advance
    Seems lean to me on the highs and high on the lows

    With pumps working I use stock N/Seat 2.0mm with black spring gives me 19-21psi pop off(usually but needs checking with pop off guage)
    High -165 closed on the adjusters
    Lows 87.5 adjusters open 1.5- 1.75 turns
    Idle set to 2800rpm out of water

    No pumps used I use all above except 95 lows open the same.

    162.5 mains
    3/4 out on highs
    1-1/4 out on lows

    -this is with acc pump cam removed (not working but in place to use as a primer for cold start)

    Get your timing advanced 2 degrees by a local dealer.
