Tach Gauge Not Working,,,got engine started!!

[P Moore]

OK,

I have the engine back in and running, but a few problems....
Its seems to be idling very high....(car is in ireland now on 95 octane)
I also have no Rev Counter reading, i was told that my MSD box messed this up on me, its a 6AL with the MSD Coil and MSD Tach Adapter.....
All i have checked on the rev counter so far is the connections on the back of the clock and they seem to be ok....

Any help or guidence would be great...
