Hi all!
I have the same Old Henry problem, an small vibration live in my engine since two years ago. AM SURE IT IS THE FLYWHEEL BALANCE, when I disassembled my engine I change the original clutch for other no-original one.
I asked the mechanics to balance the clutch/flywheel, "SAYS, It is not necessary because in Old car it is not important"
After assembled the engine, literately i could prepare a "milk shake for my Kids" and a Martini for me!
Well, nowadays that vibration calmed down a little, but on the road I can not pass more than 80Km/h. Once I posted this item and checked wheels, carb, dist, suspensions etc.
I fell that I must take care my engine not running in high speed..perhaps I am in a mistake.
I post pics what I installed.
Thank
Hary
