Review on π Optimized Petrol Engine Compression Tester Kit (8 pcs) and Universal In-Line Spark Plug Engine Tester for Automotive, Car, Lawnmower, Small & Big Internal/External Engines Diagnostic by Dustin Keller
Inaccurate Best Ignition Tester
The kit itself is well built and the price is great except it's not accurate. I compared it to MAC and Snap On in three different tests. The last two were only a few pounds per square inch apart, but this one was a long way off. The tester I bought showed 115psi, 124psi and 122psi. MAC Tester 156psi, 159psi and 159psi. Adjust to 155psi, 156psi and 156psi. This was all done on a Kawasaki FD620D 18hp V-Twin. Unfortunately I missed my return window while waiting for other parts to arrive. Maybe I'll just swap out the pressure gauge.
- Great Design
- Legacy Model
