    High Revs at idle

    It's happened twice now. After a short blast (foot to the floor) my 3B idles at 2-3000 revs! I depress the clutch or put her in neutral and the revs don't drop to the usual 900 revs. The first time, I switched her off and restarted and she returned to normal, but that didn't work the second time and she was okay after about 15 minutes of driving. Any ideas?

    John.

    Clean the Idle Stablisation Valve with isopropyl alcohol.

    Do a search on the forum for ISV , there are many threads showing it's location and how to clean it.
