AFAIK its the same dist setup as a 7A, i had a similar problem caused by wear of the original plastic gear which tend to fail completly after a while. The fix is to source one of the metal gears (can be found on ebay) and fit it along with a few thin washers to take up all the slack, you should get about 1mm play left/right and even less up/down then. With the wear your open to all sorts off issues with ignition scatter etc...
