Install new condensers and points, making
sure the new points are clean and that the
backing plate is clean for a good ground
connection. The green wire goes to the front set
of points and the black wire goes to the rear set
of points.
7. Adjust the point gap and ignition timing.
Periodic inspection and adjustment of
ignition timing is necessary to compensate for
contact point and rubbing block wear. Failure
to do so will result in incorrect ignition timing,
which in turn may cause poor performance,
overheating, knocking or engine damage.
Clean the contact points and adjust their gap
before inspecting ignition timing.
There are 2 ways to inspect ignition timing:
(engine not running) a n d dynamic
(engine running). Dynamic timing inspection
is preferable if a strobe timing light (Figure 73)
is available, because it checks timing under
actual operating conditions a n d allows
inspection of the ignition advance function.
Check t h a t t h e i d l e speed i s w i t h i n
specification before inspecting dynamic
timing, because a very high idle speed will
begin the ignition advance process and give a
faulty reading; see Idle Speed in this chapter.
1. Install the spark plugs; see Spark Plugs in
this chapter.
2. Remove the ignition timing cover and
3. Hook up a stroboscopic timing light to
cylinder No.
or No. 4, according to the
manufacturer's instructions.
4. Start the engine and allow it to idle. Shine
the light at the timing inspection marks. The
" F
mark for cylinders No. 1 and No. 4 should
align with the index mark at idle (Figure 74).
For clarity, the timing marks are shown
bvith the timing plate assembly removed.
Ohserve the marks through the upper
hole in the timing plate.
5. If the "F" mark does not align at idle, loosen
timing plate screws (Figure 69) and
rotate the base plate as required to align the
marks. Tighten the timing plate screws and
recheck the timing.
6. Increase the engine speed to 3,400 rpm and
check that the pointer falls between the double
line advance mark (Figure 75). If the advancer
does not work correctly, refer to Ignition
Advance Unit in Chapter Four.
7. Connect the stroboscopic timing light to
cylinder No. 2 or No.
Shine the light at the
timing inspection marks. The
mark for
cylinders No. 2 and No. 3 should align with the
index mark at idle. If the
mark does not
align at idle, loosen the 2 front point mounting
screws (Figure
and adjust the point gap to
