okey dokey I've got my bus up and running but it seems the temp 2 sensor screwed into the cylinder head by no.3 isn't doing its job properly! I've been looking online for a new one for a while but they seem to be nla. Any of you lovely folk out there got one lying around or maybe even still got one fitted to your engine after converting to carbs? I've been thinking of using a variable resistor mounted on the dash if I can't find one. Anyone tried this? Apparently it'll help with head temps as you can richen up the fuel on the go..
