OS-12 CV-R -- Need help w/ shaft length.
I not sure of the exact length I had to cut it down to. I just used the pilot shaft as a guide. Although I've had the motor for over a year, I've probably only put 1 gallon through it. IMO, it's a very good motor. It's very reliable and has decent power. I wouldn't worry about the fact it doesn't come with a warranty. Just keep it clean and don't run it too hot, and you shouldn't have any problems. I also have the .15 cv-r, which I run in my MT.
