This engine is for pressure washers and log splitters only, it will NOT work for lawn mower applications. This engine runs well and does NOT surge, click, tap, knock, smoke, etc. It is a good running engine. Gas and oil was drained and air filter was removed. You will need to add oil and an air filter prior to use, or you will damage the engine.

I've uploaded a video to YouTube of it running which can be viewed by this link: https://youtube.com/shorts/5UT8m4__cuA?si=TGlVqAcV-FfTuGL-
