George, thanks for your drawing. I'm going to re-design my plug and see if I can get some sort of bush soldered to the end. High temp adhesive isn't going to work very well in ptfe I suspect.
You are more organised than me looking at your drawing!
Ian, the valve heads are 8mm dia, and the stem big dia is 1/4".
I happened to have the springs already, but they originally came from Entex Springs in Nottingham, UK. Whereabouts are you?
I would be wary of giving you the exact spec at the moment as I have no idea if they will be strong enough for the job.
Valves take 1.3kg (2.9lbs) to just start to open. I suspect the valves are going to bounce at high rpm but I'd rather start off
too soft than too hard.
Cheers.
