Response to well played sir, well played

the ICV in such a small space.

ive thought of reaming out that half of the valve to create the step, but then there aint much room for the spring. Cutting the check vavle body itself down abit will help, and maybe a smaller (less tall) spring.

Looks like some kinetimechanical experimentation is in our future
