Thoughtful reading.

Mitch's comment re flywheel not seen when I posted this. I'll stick to my comment. Agree about the fan. |
Think I had 7lbs removed off my Amazon Derek and no problem at low speed. Think they are overly heavy to start with. Think mine was still 17lbs after machining.
Good suggestion on the clutch and flywheel balances together.
Amazon cars also do a vid of lightening the steel timing gear, I won’t be but if you were building a engine that might be an idea as well.
