Hi again. Apart from Wallace (land rover) I've also got a '76 vw bay window camper, 2000cc air cooled with twin solex carbs. local runs, about 22-23 mpg (imp) longer 26-28 mpg, and a couple of times on motorway tailing truck with a tailwind, I got 33mpg. Now all these figs are above avg (excl last one!!) more like 17-18 local and 23-24 on a run, so I must be doing something right. Now can I run a vacuum gauge on an air cooled bus, and will it do me any favours? I haven't driven it for about 3 months, as its winter, so not tried the eco thing, but vw engines like to be revved freely, and not lugged at ALL, so would a VG encourage me to drive the bus wrongly.
