    just a mention my float height was very high from the oem, caused terrible gas mileage until i dropped it to the max side of the spec.

    Definitely check the float height. If I'm reading you right your needle is in the more rich section of the needle. I'd drop the needle. Raise up one clip position (3rd). What mix ratio are you running? My 14 tc250 calls for 60:1. You could just be oil rich in your mixture if it's causing it to splooge out the silencer.

    I fear I may have opened a can of worms.

    Other than a quick blast on one of the TCs I know nothing about them but all the guys that own one here in the UK use a Suzuki needle in their bikes from the conversations I have had with them so maybe worth a search.

    Thanks Guys. I'm running 50-1 amsoil interceptor.

    I installed the N1EH needle (leaner) on 4th clip, 160 main and 40 pilot. All Husky parts
    that came with the bike. It runs much cleaner. Plug looks good and no spooge. Yea

    A buddy did suggest the suzuki needle and is sending it with a 168 main. He said use the 42
    pilot with the suzuki needle also. I'll try that when it comes but it seems to be running
    pretty well now.

    I worry about running too lean..but seems ok. Not trying to start a jetting war. Just
    curious what everyones experiences have been.

    I will report back the results with the suzuki needle.

    Thanks again for the replys.

    I had the float out but didnt change anything. Curious though..how would I change the height?

    Didn't see any adjustments on it.

    you bend the tab down with the carb upside down this will lower the fuel level in the bowl and lean it out every where

    quick and dirty check is to turn on fuel and slowly tilt the bike to the side and look for overflow of fuel from the bowl overflow line. Cant say an exact angle but mine leaked at like 10 to 15 degrees, it would leak when bouncing down the trail. mine is somewhere 30-45 degree now before leakage....this is only a quick and dirty field check. Setting the level properly to the correct number is proper. I forget the number but I thinks its between 6-8mm I set mine to the higher number side of the spec (lower float height).

    It doesnt leak til its tipped to about 45 degrees, Another dumb question...how do you measure the float height?

    Thanks Troy

    After riding it today its still rich. I have a line on a suzuki DW needle and a 168 main.
    Will check the float also.

    Supposed to be a good setup..we'll see. If that doesnt work probably go with the JD kit.

    Much better.. now runs clean everywhere. Heres what did it...

    Suzuki DW needle on 3rd clip
    42 pilot
    165 main

    This is how its supposed to run. Only rode for 15 minutes though. I will
    ride it longer this weekend and give a complete report.
