Although any engine/manufacturer can have good engines and bad engines, my experience with OS engines over the years has been exceptional. I still have and fly OS engines that are over 25 years old.

The latest engine I picked up from OS is the .37 SZ-H and it has run flawless from the first moment I started the engine over three years ago. I have not had the same luck with other engines (TT).

The LA series engines by OS are just that, cheap engines meant for the entry level pilot. I have an old .46 LA and it ran okay but was nothing spectacular, I knew that when I bought it. Bottom line, you pay’s your money and you get what you pay for. I’ll always use OS engines as my go to engine period.
