Also, unless the throttle is engaged, the choke tends to stay at the high idle position. Driving away allows the choke coil to position the choke in the proper position. Leaving it at idle without the gas pedal being pushed keeps it at idle too long. It's supposed to kick itself down to lower and lower idle with time, but the pressure of the throttle springs often overpower the choke element, and keep it at the high idle position. BTW, for those unfamiliar with the time factor. The choke coil heats up and rotates the butterfly valve from the closed (start) position to the fully open position (run) based solely on the time the ignition key has been in the RUN position. No fancy feedback mechanism, just a heated coil. This can be a problem when the car won't start, the ignition key has been engaged a lot, the choke coil is hot and the choke is fully open, all of which make starting even harder. At this point you are back to the ol' pump-gas-to-enrich- the-mixture start routine, which requires a deft touch, unless experienced. You have to wait until the choke coil has fully cooled off to do any choke adjustments. Jeff '67 Sqbk -----Original Message----- In Sue's defence, VW say you should drive the car off right away. It's more important with carbs as the auto-chokes come off with time rather than engine temp, so if you leave it idling, the chokes are fully off and the mixture is too lean and the idle too slow for the still cold engine. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
