Idle Speed

Just noticed something strange about some figures regarding correct idle RPM

Idoits guide: 850 rpm

Haynes Manual: 800-900rpm

Original car's manual from VWA: 550rpm

just though this was strange, I need to tune it up tommorow and reckon I might go with VW's number but why would these other figures be different?

the engine is an F series 1300 SP all original

but wait theres more, here are some VW manuals from the samba, both for the 1300, 2 different figures....

first one is the same as my one from VWA: http://www.thesamba.com/vw/archives/manuals/66bug/50-51.jpg

however, the second one appears to be from 1965, in that case the 1200 is at 700-800rpm... and could be an overlap the first one listed is from 1966 and i definately for the 1300...

i'm still non the wiser though

An old mechanics method on generator equipped cars was to screw the idle down until the gen light on the dash just starts to glow.( screw back and forwards a few times to get the point accurate) Then screw it back up a quarter of a turn.
