What has happened is someone has had the drive dog off the shaft of the
distributor and put it back on 180' from where it was when it came from the
factory. Just knock the pin out, reinstall 180' and you should be good to go.

Subject: [Mgs] MGA Distributor Problems


I recently had my DM2 distributor out of a MGA 1600 with a three main
1800 engine and encountered two problems.

1. When the points were adjuster to the farthest open setting, the cam
would still not open them.  I had experience intermittent  lack of power
on acceleration under load.

2.  I replaced the distributor with another used one.  When I set the
engine at TDC to static time the "new" distributor (DM2), the rotor
points 180 degrees away from the #1 wire.  The distributor drops in OK.
Of course the engine does nor start.  there is the occasional backfire
and rifle out out the tail pipe.  I even dropped in a spare 25D
distributor and it also points away from #1.

What is going on?
