    94 SL650 factory carb settings

    Hi,
    My ski is from CA and a local AZ jet ski mechanic told me to adjust to 3/4, 3/4, and 1 . Is this pretty close to factory settings? I searched and only found settings for 93 and 95.
    Also, what is best spark plug for this ski? I was told on a previous thread to go with NGK-R
    Just making a couple of last minute adjustments for a lake test tomorrow. thanks

    I have looked for over an hour on this site and still can't find the factory carb settings for a 94 sl650. Can someone pass this my way if you know where it's at? as stated in my previous thread a jet ski mechanic I know locally said it was 3/4, 3/4 and 1 for high speed screw. So that is what I set it at. I will be going to the lake with my tools in the morning and would love to get this right. Thanks
