Hi
I'm new to this site and found your postings while looking for info about other Armstrong-Siddeley engines. I am building a large scale model of a Lynx, which was the smaller and earlier brother of the Cheetah. I can't help with your restoration but hope by now it's well under way and maybe even finished. If so, congratulations. Did you get any bits from Eric Offen who I know had one of these for a while?
I am wondering if you could help me: I am interested to know how the design of cams and valve timings developed during those early years. Before making the cams for my Lynx I want to be sure as possible that they are right as I have no detail drawings. Would you consider sending me the timing events in degrees for the Cheetah if you have them and also a good photo of the cam ring (taken face on)? The other thing is the tappet clearance if you know what it should be or have worked it out. Maybe all this is still unknown to you in which case please forget abut it.
Thanks anyway.
