Review: 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!!
Review: Bolt holes are not threaded - Very good quality start's easy bolt holes are not threaded
