The dwell angle should be 60 +- 3.
First thing to do is to make sure that the right distributor is fitted.
The ignition timing depends on type of your engine specification. In case
of an
86 mm engine the summary of static, advance due centrifugal control and
vacuum
unit should not exceed 26-27 degrees.
If thereīs a wrong distributor fitted to your engine donīt wonder if it
doesnīt work.
The distributor for the 83 mm engine has a advance timing due weights and
springs
of max. 15 degrees. Thatīs max. 30 dregrees timing on the crankshaft.
You must add static timing (4 degrees) and the advance due vacuum unit (
max. 15 degrees).
Thatīs too much advance for an 86 mm engine .
The Lucas Part No. for 83 mm engine: 40403, 40480, 40698, 40783, 40850
86 mm : 40735, 40795
