I was having similar issues. One thing you can do is take the fan switch out and test it with a VOM and a pan of water on the stove. The one on my car would close at 85C.
Someone before me installed a cut-off switch like the one in the picture in the previous post on the firewall in the passenger side footwell. I'll get a photo of it and post.
Hey Jimmy, I've got a cross flow with clams and could meet you at an area park. It would be later in the month due to scheduling stuff. Too bad the British Car Fayre is cancelled for this year, but quite understandable.
The Hemmings listed car does have one feature that may indicate it was a S2 originally. The dash does not have the corner bracing I associate with the S3, also is there any research into the VIN? FWIW
One of my carbs will slobber some, I ran the car W/O the K&Ns and the clam on that side needed clean-up after a blat. That may have something to do with the amount of overlap between intake and exhaust. I've put the filters back on, but it did sound good unfiltered.
Sounds like it's time for a pair of skinny driving shoes.
As to parts inventory and missing stuff, Caterham has been doing this for a few years, one would think they would have it figured out by now. :banghead:
Also, Have a Blast!
