    1100 - Low Speed – 1-1/8
    High Speed – 7/8

    760 - Low Speed – 1-5/8
    High Speed – 3/8

    Settings ^ are based @ sea level

    Do not tighten down on the adjusters too tight as you can damage the seat
    Make sure do a compression test to get a baseline on your motor.
    Use an aftermarket tach to check actual RPMs
    Be meticulous on carb assembly, cleanliness and setting up the carbs.
    If you run premix, make sure you measure correctly, incorrect measuring can lead to an altered oil/fuel ratio and affect tuning, running and engine health

    What do you have for a 94 700 waverunner 3 for factory high low settings? thanx in advance....

    I spent a few hours looking for information confirming the factory settings. Are the ones you listed from the factory or are they handed down? Only reason I ask is there is a lot of opinion on what the factory settings are, and I am curious who has the real "official settings". also i'd hate for someone to adjust their craft too lean and run it for a weekend on bad info. thanx.
