Title: 1920 3½hp Valve Springs
Post by: beaumy on December 16, 2024, 10:16:26 PM
Good evening everyone,

I am currently overhauling the valves, guides and springs on my 1920 3½hp 'square' engine. I would find it very helpful if any of you kind people with a similar machine would be prepared to measure the fitted length of their valve springs with the valves fully closed.

I am unsure as to the position of the valve spring seat/insulator in relation to the cylinder/valve guide.

A photo wouldn't go amiss either.

Many thanks in advance.

Kind regards,

Pete
