Just blow a hole in the piston; that'll lower compression in a hurry.

The trick is blowing an equal sized hole in all of them so the engine remains balanced.

I think you need to use my method as described in an earlier post, screwdriver and a mallet for an even and consistent hole.

Hmmmmm I will need to pick up a calibrated mallet to ensure consistency.

Short and sharp with focus, no messing.
