8 degrees for economy or 10to12 degrees for performance.you will know if you gone to far if it starts to ping.

I have seen balancers actually twist and throw off the timing markings from where they should be. I now do my timing on old engines the quick and easy way. Retard then advance and find a sweet spot in the middle. A few times doing this and test driving you can get an engine running very close to perfect. Only after I have the engine running great will I put the light to it and check the markings.
