The OH160 ignition came in 2 flavors. One with points that you can put a Nova ll kit on. The other flavor was pointless electronic ignition. The systems use different flywheels. The electronic used trigger pins on the flywheel. If you can find a working electronic ignition module for sale they are usually between 200 and 300 dollars. I have an OH140 engine out in the barn. One of these days gonna drag it out and refurb it. Been saying that for years...
