Re: How to measure poppet valve spring pressure

Thanks for the replies.
Hmmmm. A little confusing to me. I see how to measure and adjust the height using a drill bit. The only way I can think of doing the pressure is with the poppet out put desired weight on it and see if it moves desired distance. To do that, I would have the spring and poppet assembly upside down and just place the weight on it and see if it moves the desired distance. But I would have to account for the weight of the poppet. Or should I rig up some method of blowing air against the poppet and a ‘seat’ made of tubing and somehow measure pressure. There must be a simple way that I am just not seeing. Maybe I will adjust the height and hope for the best with the pressure, unless the spring has been bent it would not have changed much, no?
Again, thanks for your replies.
