I was reading a thread about harmonic balancers and it got me thinking - When I bought my 964 engine it had no harmonic balancer so I sourced a secondhand one and was planning on simply fitting that.
One thing that I have noticed about them is that they have different amounts of drilled holes in the front presumably for balance.
This must mean that the one I have bought is balanced to a different crank and needs to be rebalanced.
Does this mean that the best way to balance it is to dummy mount the flywheel and the pulley with harmonic balancer to the crank either in V blocks or in the case half and try to find a 'low point' where it settles then carefully drill the harmonic balacer a bit at a time until it seems weight matched or is there a better way that anyone knows of?
