Well, the OS 46 AX ABL is the newest version of the OS 46 sized engines, and for $109 at Tower, this is a great buy, and well worth the few extra bucks you may spend on a less expensive (note, I did not say cheaper) engine.

I had an Evo 46 and it ran pretty good. I hated thier 61 and 100. Both ran lousy, when I could get them to run. But the 40 was a good engine.

But, after the experience I had with their 100, I prefer to stick with OS engines. I have several and all of them, and without exception, they all run like clockwork.
