Hey Minn...the idle is actually hanging on the higher side for a few seconds, then coming back down.
Exactly... You have a combination of two problems
1 - The idle is set too high
2 - The low end is rich
What's happening is, you go to idle, you should almost immediately get the low RPM that you want, but the idle is set too high so you're not.
But now, as the engine idles, it's getting too much fuel, so the RPM slowly drops. If you turn the LE adjustment needle in, you will hear the RPM rise. Then, you'll need to lower it with your trim, AND you'll probably need to richen the High-Speed needle too.
