Hi. I have a Howard Gem with JAP 600 side valve engine, for which I need new (or perhaps good used!) valves. They bear the number 7524. I have one one valve which could be used as a template. So, two questions!
1. Do you know who might be able to supply such a valve, or modify a similar valve from a blank?
2. Does anyone know the actual dimensions of this valve? – if one is to be made it would be better to know these rather than measure with vernier calipers.
Thanks for your help.
