Vanguard flywheel compatibility

Hi, new to the forum, looking for a little information. I have a vanguard 16hp. The ring gear on the flywheel is about half stripped of its teeth. The replacement ring gear for this flywheel is no longer available, nor is the flywheel, but there is a kit with a new flywheel and a different cover. It is too pricey for a 21 yr old mower. Not worth the investment at that price. Not a lot of used flywheels for these either. My other option is to use a flywheel I have from a vanguard 18hp engine. It is the type with the bolt on fins. It does bolt to the engine, and the driveshaft coupler will attach to it. I'd have to modify a few things on the cover, but that part isn't a big deal. My question is are these flywheels zero balanced, or do they act as a counter balance to the crankshaft? If they are zero balanced than I should be fine, but if balanced to the weight of the rotating assembly I'd probably throw things out of balance. Anyone on here have any expierence with this? I currently have the flywheel installed on the 16hp engine, but don't want to start it if it will throw the engine out of balance.
