<VV> timing mark jumps help

[Charles McKinley]

I'll second Jim's suggestion and add that as part of that exercise,  
you should check the vacuum advance hose and dashpot and the  
distributor weights and springs. My 63 had the old weight springs all  
stretched out and pretty much non-functional, so I replaced them -  
much better.
