seems ok. The display of the engine being tested for stability is a bit shaky, and there are loose wires inside the case that cause it to shut down when shaken. I'll probably open up the case and do some soldering to fix this problem. The 2/4 time setting is practical. I'm using a 4-stroke engine, but it uses a useless spark ignition system, so the 4-stroke setting shows twice the actual RPM, while the 2-stroke is accurate. This is normal with my engine.
