Cheap Ebay compression tester vs Laser compression tester * DONT BUY THE WRONG ONE*

Hi everyone, hope you keeping well and safe. So after my last video where I compression tested the GOLF I thought I had to make this video because I stumbled upon an issue with these cheap compression testers. In this video I tested both a car engine and a chainsaw 2 stroke engine and the results are very surprising especially on the chainsaw where one of the cheap testers didn't do too bad on the car but did really bad on the saw. Thanks for watching and keep safe. #diy #machinemart #laser tools
