PART FOUR - IGNITION
This has been extensively discussed in these forums.

The early engines were fitted with conventional magnetos.
At some point - probably about 1962 - Scott Bonnar adopted the then new
Wipac Magister system.

Member Willingworker has identified the sequence as this:-
Scott Bonnar's 155cc 2 stroke Model 201/202 had 3 different magnetos fitted.
Up to engine number 201-4001..............Wico magneto [Pic 1 in attached]
From 201-4002 to 201- 6193.................Wipac magneto [Pic 2 in attached]
From 6194 onwards................................Wipac Magister magneto [Pic 3 in attached]

"From this it shows that over 6000 engines were produced before the Magister
was introduced. Old S-B employees remember that they had trouble with the Magister.
It does seem strange that some engines without a Magister have a hole drilled in the
aluminium shroud. This information comes from a late 1960s Spare Parts List."
