Flywheel Teeth Count

I purchased a Lycoming IO-360-A1A engine less the flywheel. How do I determine what flywheel to purchase? I have seen people talk about the 149 tooth and 122 tooth flywheels.

Where can I go to find out which flywheel I need to get?

I'm planning to go with a CS Prop (today), if that makes any difference.

Some info here might be of use. Ensure starter gear matches with flywheel ring gear.

Good luck!

I was in the same boat as you. I called Dick Waters at http://www.airtecinc.us/ and he answered my questions and sold me a brand new flywheel at a very reasonable price. He has also helped me with other questions I've had about my IO360.
