Excellent install, good engine

This motor came packaged very well. As long as you know a little bit about installing an engine on a push mower it's very quick work. It's easy to mount onto a chassis, there are a few different holes to use. Make sure you put motor oil in it and break it in properly. It has been running well since, it was an excellent replacement for a Briggs & Stratton motor.

Great Replacement Engine

I got this 173cc engine to replace the 28 year old tecumseh engine on my craftsman eager 1 push mower. Took about two hours to install, including tapping two of the mounting holes. After adding gas and oil, It started right up on the third pull. I'm most impressed by the power of this engine. I hope it will last as long as the old tecumseh.
