The earth wire is required to provide a good solid ground between the top movable points plate and the distributor body .
You may get intermittent poor running if it is not fitted .
One end of the earth wire is secured to the wee screw which holds the condencer to the top plate .
The other end of the earth wire is secured to the screw which holds the bottom points plate to the distributor body .

DISTRIBUTOR ; HIGH TENSION LEADS ; FIRING ORDER
Fit the cap
The spark plugs are numbered from the front of the engine going backwards .
Number 1 spark plug is at the front of the engine
Number 2 spark plug is the next one in
Number 3 spark plug is the next one in
Number 4 spark plug is the next one in
The Firing order of the leads is 1 , 3 , 4 , 2
The rotation of the distributor is ANTI-CLOCKWISE .
The lead nearest the engine at the front of the cap goes to the Number 1 plug .
The lead to the left of that goes to Number 3 plug
The next lead goes to Number 4 plug
The last lead goes to Number 2 plug
If you have a 600cc engine the the same principle applies EXCEPT The rotation of the distributor is CLOCKWISE .
The lead nearest the engine at the front of the cap goes to the Number 1 plug
The Firing order of the leads is still the same 1 , 3 , 4 , 2

DISTRIBUTOR CAP FAULTS
One problem with the distributor in damp weather is due to a build up of
a grey coloured crusty deposit on the 4 distributor terminals .
This needs to be picked of with a small screwdriver or something similar
taking care not to scratch the metal as you do it .
