Get this if your mower needs a new engine!
Great price, easy to install, and started right up. It purrs like a kitten. Several have complained about no threads. Big deal!! You can simply nut and bolt it with a lock washer, or like I did tapped the threads. It took me a few minutes. In California we can no linger buy new gas mowers, so I just replaced the engine when the old one died. $200 what a deal!!

Poorly packaged!!!!!!!!!
Item was either poorly packaged or thrown around by delivery personal. Wasn't sure if I should send it back or give it a try. Opted for the latter and got Lucky. Runs like a charm.

Great Replacement Motor!!!
The engine arrived promptly and was packaged well avoiding damage which is commonplace now in shipping. I bolted it up to a toro self-proppelled mower with original self-tapping bolts and it went on without any issue. The pulley and blade holder also went on without any problems. After adding the appropriate amount of oil and gas, I pumped the primer bulb a few times and pulled it and it started on third pull. Runs great, better than original engine that came on it!

Motor is doing great. Easy to start and runs smooth. The only thing it needs is a tube for adding oil.
