The thought has crossed my mind, not ready to quit on it just yet though! :confused:How about just putting that 98mm cylinder on the shelf and calling it a learning experience?

Thanks SFO,
I hadn't considered the spring height, and I don't think they did. The shop re-cut the seats for Kibblewhite oversize valves, and ground the original shims to regain the correct clearance.. (Well, a vaguely correct clearance, I still had to change shims when I got it home). I think it was just a sloppy job - but you live & learn!

Certainly does, thanks Bill...Hope this helps...

Thank a pinhead accountant for that decision because no self-respecting engineer would design it without studs if given the option.
