Review on Lisle 20530 10mm Spark Plug Adapter: Enhancing Efficiency and Compatibility by Ryan Person

Garbage. I tested a brand new chainsaw and the reading was only 95psi. I think this caliber is at least 15-35lbs lighter maybe more so what's the point? Money out the window, I'll get back to you tomorrow. EDIT: I returned it and then borrowed a compression gauge from a friend and tested the same chainsaw again. This time I got £130 which is almost right so the Lisle 20250 ended up being £35 less than I expected. I'm glad I returned it.
