"D" shaped screwdriver.

Lots of Chinese carbs come with an idle adjustment screw that is "D" shaped. Anybody know where I can buy a screw driver for them?

A few years ago, I went on Amazon and found a whole little kit that came with whole assortment of carb. adjustment tools supposedly for all the small engine carburetors one might encounter. The tool you need would undoubtedly be included in the kit. As I recall the set was not very expensive.

Another vote for Amazon. I got a set a while back to adjust my string trimmers.

Yes I have those....for little 2 strokes. I am looking for one for clone type carbs.

I didn't realize that there were adjustment screws like that on 4 strokes. See, if you're not careful, you can learn something new every day!
