    FL250 Carb Jetting

    Hello Fellas,
    Its my first time post here and looks like I found a good site.
    I am doing full restorations on two FL250 Odysseys for a client and I am having trouble finding a jetting chart for these carbs.
    They are KEI HIN carbs, couldnt find any other numbers on them. They had the 120 jets in them before with wire someone had installed to lean them out apparently. I am in Utah at 8600 feet I believe. I need to find out which jets to use so these machines are snappy and client is happy. Could someone please spend a little help time with me? I can post whatever pictures necessary.
    I appreciate it much!
    -Wes

    Welcome to the site.

    You can probably get your base settings from your local Honda dealer - I would imagine they still have a parts fische in the computer for the old 250's.

    Also, get in touch with Sudco - they are THE carb specialists.

    Do not forget to tell the clients if they jet them lean for snap they need to buy pure gas only and not gas with ethanol in it as if they get gas with too much ethanol (its not regulated very good and the amount varies per batch) you will melt down a well tuned two stroke thats jetted to run hard on straight gas as ethanol leans them out.

    With a two stroke anymore I will only get older mild performers and tune them to run mild as hard running two strokes use too much gas VS a good fourstroke engine these days.

    With older stuff its just easier to run it easier if you wish it to last or fork over cash for race gas or the best thing is find a gas station that sells gas with no ethanol. They are out there just gotta find them.

    If no gas only stations exist where they will be buying gas then jet it for the worst (largest amount of) ethanol gas there and tell them thats it if they wish to ride them home and not tow them in.
    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Lets hope the next guy repeals NObama care along with the rest of the stupid crap this blight on our windshield has done.

    hi guys! i'm new here, I'm venezuelan. I'm about to buy a honda fl250 but is not working, the guy who's selling it, told me that the problem is on the pull starter box specifically is the exciter coil the one that goes inside of generator. but there's another one, the lamp coil.

    i dont know much about mechanic, so i was wondering could i use the lamp coil as a exciter coil? if i do it i may lose control over the switches or are they depending of another system? at this point i dont know if there is a cdi involved . .

    i will appreciated the help a lot.

    sorry if my english is not good i'm a spanish speaker

    Welcome to MBN!
    Your english is great - no worries at all.

    No, you can't use the lighting coil. It's not going to have the correct wiring (number of winds around the core) and it's timing (position in relation to the crank) is out.

    Sorry.
