2005 Honda CR125 carb basics

[400ex4ever]

Can someone take a photo of thier carb and give a breakdown of the differents agjustments screws. My son races quads and I recently swapped out a CR85 for a newer CR125 and have no idea how to get it tuned/jetted correctly, yet. My service manual in on its way but I wanted to give it a test run this weekend at the track. Please help.

This is what it looks like:

Also, can anyone tell me where to get those rubber dampening exhaust springs. The rattle is killing me.

Thanks,
Eric
