    Rebuilt cdkII carb and can't get rid of dribbles.

    Ok. I'm about to pull my hair out. I have a 1999 1050 with acc pump.
    The mag and center carb were dribbling.
    I totally rebuilt the carbs went as far as to put in new needles and seats as we'll. checked the pop off pressure. The mag and center carb are at 24 psi and the pto carb is at 23.
    I set the float arms to .060 below the casting.
    still had the same issue as before rebuilding.
    I then adjusted the float arms down to where the white tab was level with the carb body next to it. Still have dribbling.
    So I guess my question is what next? I'm not sure where to go from here.
    Thank you for any input you may have. Edd

    Looks like fuel restrictor is clogged up.
    It's in return outlet of mid carb. Its diameter is very small (.020") and easily gets blocked by build up.

    Great. I was thinking it was something along those lines. I assume I access it by removing the center carb return fitting? Or should I do it from inside the carb? Thank you for the fast response now I can start to turn off my brain for the evening. Thanks edd

    You'll have to remove the brass fitting to get to cleaning it. Use a small wire or better yet a small drill, they'll have to be .020" in diameter or smaller of course.

    So here's what I got:

    Checked the return line and it did not appear to be blocked.

    I went ahead and drilled it out replacing it with a .020 jet placed in the hose right where it attaches to the carb. I reset the float arms to .060. This time all 3 cards dribbled.

    I pulled the jet in the return line and it was clear. I adjusted the float arms down to where they had very limited movement and the pto carb dribbling slowed down but the other two are still dribbling.

    I tried removing the fuel cap and that seemed to make no difference.

    I am willing to try anything at this point, give me any suggestions and I will try them.

    As a side note, as soon as any throttle is applied it stops dribbling.

    Removed the carbs this morning and tightened up the float arms on the pins. The mag carb had the most play the center had a little less play and the pto carb had even less play.
    After doing this my pop off went up to around 25 26 psi
    Adjusted the float tabs back to .060
    thought for sure I had it this time.
    still dripping in all 3.
    Lowered the float tabs a little and still dripping.

    May just have to live with it the way it is except it's driving me nuts. Can't stand when something isn't running like it should be.


    Any ideas? Anyone?

    <<the old guy remembers an ancient scribe, on flotation foam I believe, which tells of adding a second check disc to a mikuni fuel pump to avoid dribbling on engines that have above average vibration....>>

    that was for the mikuni's where the jet block faced the jugs.you'd double or triple up the check valves (flaps) on them to help.lots of guys would just turn them around and face the jet blocks out or forward.
