Hey guys just wondering if anyone can help? When I rev my escort then let off the throttle the car continues to rev. It is running an 1800 zetec on bike carbs. We have disconnected the throttle cable so I have ruled this out, the only way to rev it up then return it to idle is if you turn the linkage by hand on the carbs. If anyone has any ideas on how to rectify this I would be very grateful! Thanks Rob.
