    Well, the shiny silver are the longest, followed by the black, which are a little shorter, followed by the gold which are a little shorter, followed by dull silver which are the shortest....

    I couldn't tell the dull and gold apart except for length.... and I looked for a half hour at those damn springs..... just last night, under 3 different lights.

    Guess I'm blind.

    I guess...

    Gold is the easiest to tell,its the 2 different silvers that fool most people...

    The 95 spring is wound counter clockwise & all the others are wound clockwise looking at the ends,I use a small magnifying glass cus I am old & going blind.

    Hey great info on the wound opposite thing. And, one of my three ways of looking under light last night, was under a magnifying glass.... LOL..

    If I didn't have all four grams in front of me, I would have never got stoned!!! LOL!!!! It just sounded right and I don't even smoke anymore! Anyways, if I didn't have all 4 in front of me to compare lenghts I would have never known which was which.

    don't forget this one.

    95gm - MIKUNI #730-03034 (THIS SPRING IS FOR SEA DOO BN 461 CARBS ONLY)

    i have no idea what the difference is and have rebuilt carbs using non-mikuni rebuild kits supplied by owner and the 95g spring included in kit without any problems. when i order individual parts for seadoo carbs i always order these instead of 03033

    what is the difference - anyone know??

    That 95 gram Spring CCW winding is the key to i.d. the part.

    I just go my carb rebuild kit for a 46i, and my 95g spring are just like the 65g. Wound clockwise and part number 730-03034. I thought all 95g were counter clockwise. Mikuni is saying its 95g too, no just something I thought up. Any idea's?
