I didn’t mean to imply that simply removing the spring would block the piston- I meant I left the spring rather than blocking the piston. I am aware that you constantly and tirelessly work to dispell that myth about simply removing the spring or springs.

It just seems wierd to throw a piece of metal in there that is thin and free to settle into a diagonal position. I guess the piston doesn’t have room to move very far? And the blocker would drop in under the piston with the goal of positioning it as close to the valvebody as possible?
