Yea, we've got them in stock -- but not at 2001 prices. LOL
If you're going to go with the oem flywheel, get a new one. It's not worth the risk of not knowing how the previous person removed it from it's donor engine.
We've spun them over 8000 rpm often back in the day. Not that I am recommending that in any way, but use it at your own risk.
Keep in mind that there are aluminum 3 HP Briggs flywheels made for vertical shaft mowers -- DO NOT try to use them!!! They are cast aluminum and WILL come apart. I see them for sale often on ebay and advertised as a direct replacement for kart engines -- this guy/seller ought to be castrated for making such a claim!
The cast iron flywheel weighs just over 3 pounds if I remember correctly. The only ones I have here are still in the box so I can't get you an accurate weight on them.
They do help on acceleration, but will hurt momentum due to their lack of kinetic energy (rotating mass under deceleration.)
