Help me tune my bike

[newbie555]

So my bike runs good, except it wont idle well. once it is warmed up it will but I cant get it to idle on startup. I have moved the clip all the way down on the needle, and have messed with the idle screw and still no luck. It is still lean I think, definitely not rich. So I saw in the other thread this adjsutment screw.

does this help with idle?

I'm a newby too, but I have been messing with that screw a lot today so I'll comment. I'm told that is the fuel mixture screw and it did help a little with my idle. Mine fires right up first time with not choke since I backed that screw out about 4 turns. Others only do it about 1-2 turns. Backing it out should help richen your mixture I think. It sure helped me today since I put on my new cone filter and drilled out the exhaust. Good luck to ya.

That screw is the mixture screw. There should be screw up on the right side of the carb about in the middle that adjust the idle.
