idle adjustment

[Schnell 318]

how do i adjust the idle on my m10?
right now it idles at about 400 rpm which is way too low.

There is a flat-head screw on the side of you idle control valve. I'd suggest cleaning it first and then adjusting it. I have my M10 idling at 1k rpms.

Yeah, if your ICV is silver, use Ken's method.

If it's black, you have to take off one of the hoses (I forget which) and adjust the screw inside the ICV.

Is 1k rpms normal for the m10 to idle at, or do you have some mods that would require a higher idle speed?

1000 rpms is about right. Try to go for between 750 and 1000.

Lucky Bastard My m10 idles at 1000 on a good day ussualy it's more around 2,000 even with the screw all the way in. I'm sure there is a vacume leak but I haven't bothered checking all the hoses.

Does it act like it's hitting a rev-limiter when it's revving high at like ~2k?

nope, it idles perfectly smooth. Ussualy it's more aroudn 1200-1500 just all depends. The icv may be bad or who knows. It drives fine so I've never messed with it.

yo! my ICV doesn't even have a screw on it. it kinda looks like it had one on it at one point. but now it looks like its a hole plugged up with blue loctite. Is the screw supposed to be at the end of it where the plug isn't? right next to the inlet hose casting?
