Carbs with good atomisation at low air flow, e.g. SUs are particularily prone to running on. So much so, that the 180b SSS flat tops include from the factory a solenoid and air plumbing to stop it. This plumbing is NOT (as most people imagine) emissions gear. Its function is purely 100% to stop running on. The solenoid is closed when the ignition is on, but when the ignition is turned off, the solenoid opens which dumps loads of air into the intake manifolds, which leans the mixture beyond the point of combustion. You could add this (or a similar) system to your setup. Not nice aestheitically, but it works. Or go EFI, which entirely bypasses this problem. --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@;datascribe.com.au/ ---------------------------------------------------------------------
