IGNITION
Distributor (See fig. 25)
Every 3000 kms (about 1800 miles) the cam felt pad should be lubricated with a few
drops of oil and the contact points inspected to ensure every are clean. If dirty or greasy
clean them with a petrol soaked cloth. Correct gap is 0.42 - .048 mm. (0.16" - 0.18"). If
they need adjusting, loosen screw B which secures the fixed contact plate and move this
to the position which will give the correct gap. However, the contact points should be
changed whenever it is necessary.
Fig. 25
Spark plugs
Every 3000 kms. (1800 miles) check the gap which should be 0.6 mm. (0.23"). Check
also the high tension leads and replace, if necessary. The spark plugs are best cleaned
with petrol, a wire brush, and a needle for the inner part.
In fitting the plugs. make sure they are started by hand for a few turns and to complete
the operation by means of the plug wrench in the tool kit. Do not over tighten to prevent
stripping of the thread.
Checking of ignition timing
Remove generator belt cover. Check that the distributor contact points are 0.42-0.48 mm.
(.016" - 018") apart. Ensure the left cylinder (2) is at its compression stroke i.e. with both
valves closed. Rotate the generator pulley on the crankshaft till the slot (fig. 26)
Is opposite mark A traced on the timing cover.
In this position the points should start to open end to ensure that they do so use a timing
light which will light up at the exact time the points start opening.
If the points start to open before or after the mentioned point, slacken distributor securing
bolt C (fig. 25) and turn the distributor to the right or left to the position where the points
start opening at the proper time.
The cylinder number is marked on the distributor cap as follows: n. 1 (right cylinder), n. 2
(left cylinder), -bobina- = coil (See D in fig. 25).
Checking of Ignition advance (fixed and automatic) by means of a stroboscope lamp
For checking the ignition advance the crankshaft driven generator pulley of the V-7
engine has been provided now with 3 additional timing marks. When In coincidence with
arrow -A-. already stamped on the timing cover, these marks will serve to determine it the
Ignition is correctly timed.
