Value of Engine Balancing

[Ruairidh Dunford]

Would it be worth adding the Cluch cover( on an early coil engine) as well?

You might also think about the possibility of adding some clutch components into the mix as well....

Bill and Hugh,

In the case of a an Austin Seven, for the balance to be effective, you must build up the entire flywheel assembly, this includes the entire clutch. Do mark it carefully so it can be reassembled in exactly the same way as it was balanced.

The only exception to this is the clutch plate, this must be left out for balancing.

With regards to lightening the flywheel Bill - my own experience is that it makes very little difference on a standard engine. However, if you feel you would like to do it you might like to consider machining it off as was done on the Brooklands (and possibly some Cup) engines, a lovely curve - so I understand.
