Odd sound? (1 Viewer)

[fahedsharif]

When i choke the 60 in the morning, after i go back down to idle, i hear a choppy sound. As if the gas is going every other interval besides having a steady flow. There is no idle change, it sits right at 900 rpms. After i drive a little ways the sound goes away until the next morning i choke it.
Any help to figure out what that is?

probably needs a more fuel. 900 is really low for having the choke on. i would adjust the fast idle for the choke up a few hundred

Think he is saying that his standard idle is at 900 which is high. Should be around 750.
