    Taking off carb...what the...

    hello all!
    i don't post a lot...but i could sure use some help..

    this is my 1990 kawasaki 550SX stamdup i bought about 2 years ago. i noticed towards the end of last summer it was getting a little slugish on heavy throttle, so it seems im ready for a carb clean/kit.

    anyway here is the ski:


    now...as u can see from the below pic, this is the carb i tried to take off so i could work on it and take it apart in the house.
    please keep im mind im not terribly swavy with motors, i just saw 2 bolds that were holding the carb on, so i took them out but it wouldn't come off...do i really have to ptry it off? is it sealed with glue? whats the best way? or finally...am i doing something completely wrong?

    before i go any farther i want to make sure im not doing something retarded, if i am, please be kind lol
    here is the pic of the carb:



    any help appreciated guys.
    thanks again
    -Gerry

    Being the carb has probably never been taken off, it is froze on kind of. There sometimes is a felt gasket that doesn't want to let go. Provided you have unhooked all the linkage, just give it a love tap with a soft mallet. Should pop lose. I hate those style Mikuni's! Best thing they ever did was to make the SBN style. Check the filters in the pick up's in the gas tank. Check the plug wires, etc...Hope you didn't pay too much for the old 550.

    i only see 2 bolts connecting it. guess ill have to bust out the mallet.

    yeah i paid $500 for the ski + trailer. it ran really perfect all summer with a little hesitation. its not even bad, more like giving me something to do over the winter.
    its outside so i think your right about it being frozen.

    it look like a round body mikuni?
    if it is save your money and get a SBN mikuni
    those round body's are fun to rebuild

    so you're saying instead of the $20 rebuild...spend 1/5th the price of the ski and buy a SBN mikuni carb?...
