Hi, Dkveuro!

I opened the OVPR, cleaned it as best as I could, measured the circuits with the Fluke and reinstalled. (Date stamp on the OVPR 13/04 89, so I recon that it has done job well in 16 years and 200 000 km).

Got a very stable idle, and seems to have sorted out the "low" speed/rpm issues I had.
Will get a new OVPR ASAP.

Thanks, Per.
