Suzuki DT4 high speed mixture screw?

[henkee]

I have a Suzuki dt4 from 1985 i recently bought.

I found a mixture screw on the floating bowl but I can?t find any information about what it does.

13616-93900 on Fig 5 in http://www.brownspoint.com/store/pc/pdf/DT4(88-98).pdf.

After a lot of google searches I found on a briggs and stratton site that old carbs can have a high speed mixture screw on the floating bowl.

Does anyone have an idea if this is a such a screw and what the factory settings might be?

Regards//Henke

The general rule of thumb is 1 and a half turns outwards from soft stop ....

Thanks, It was just a drain plug, but it looks like a adjuster with spring, hmm strange...

Do you know what fuel mix for the dt4 1985? 1/100 or 1/50 ?
