Early 3 hp Aluminum Flywheel,,

[old shed finds]

Hey guys, any of us play with the 2 - 3 Hp aliminum flywheel more less question of advantage or disavantage for the cast iron or this aluminum? We are building a 3HP for a mini bike as we speak and I have this question?This early Flywheel is early 50s with 4 leg coil,,Zippy with this lighter flywheel,,

There are a few people here that don't trust the aluminum flywheels. I think one from the 50's would need to be inspected really well. It may also be from a vertical shaft engine and may have a different balance.
I have a brand new 3HP sized Briggs flywheel you can have for the cost of a flat rate box! This is a late style for use without the points style ignition
