I recently purchased an O-320-D2B narrow deck engine less cylinders for my RV-9A project. I wanted to use new cylinders anyway, so I was glad to find a deal that did not include reworked cylinders. My question concerns the flywheel that came with this engine. It is a 122 tooth flywheel with a pulley about 6.5 inch diameter. I know I will need a case mount alternator, but I am looking for confirmation I can use this flywheel and not have unacceptable alternator speeds. I hope to use this flywheel, as it came with a SkyTech starter. Any advice would be appreciated.
