Can you tell me the valve clearances also please?

Inlet: 0.2 mm
Exhaust: 0.3 mm

Cold engine.

However, that is for the standard cam, Anders.

The Holbay cam has slightly different settings.

The inlets should be: 0.25 mm (10 thou)
Exhausts as original: 0.30 mm (12 thou)

Roy

Thanks for that, Roy!! I'll make a note in my manual about that Smiley
Is there a different setting for the S-cam too?
What's the cause of the difference on the inlet side?

Weather over here is beautiful Tongue
Did you get a chance to identify your cam then?

- Anders

I looked at the cam, but the Holbay engravings are on the ends, so I couldn't see them.
Along the shaft was engraved an "H", an "A", a "4" and the letters "FMA". No idea what they mean though.

Here are some blurry pictures...







And an attempt at photographing a cam lobe...

I can't make it out either. The Holbay lobes are much "flatter" on the top than the standard, but looking at your photos, I can't decide whether it looks more like one or the other Huh

The only marking I can find in the standard cam I have here is "SF2".

The Tagora engine manual identifies the cam by two rings between lobes 4 and 5. I.e. nothing about markings. Depending on what "raw material" Holbay uses, it doesn't have to say anything.

If you compare with my photo here: http://gallery.dinsen.net/v/biler/Murena/technical/engine/DSCF0005.JPG.html
It does actually bear the "FMA" marking.

If it is a Holbay, it doesn't look like it needs a regrind at all.
