Hi,
I have some questions about my 99 scrambler 400 4x4.

1) I moved the needle on my carbarator up now it runs better on the top end were the problems was, but now at low rpm it doesn't have the kick? it used too.

2) Do I need to play with the airscrew? if so how should I turn it?

3) If it is idling in either reverse or drive it rolls? why is that? so i put it in neutral or set the brake.

4) Why does it do all that stuff?

5) Acouple times today it backfired when starting? that is the first time it has done that..

I think you better reset the needle back to its normal position.

Is the throttle cover on the carb tight did you lose the gasket in the cover is there an air leak? Check that stuff out hope it helps .
