Hi,
Maybee this is a better place to post the info you want...The gold mower your refering to...is in fact a Scott Bonnar 35,Model 201 series 2.The second series of the first rotary mower made by SB.The 3 wires you have are from the coil,they are joined via 3 x screw fittings that run to the secondry coil."Magister"then on the to spark plug.You will need a secondry coil,to run this mower,as for a spare,Ive only ever seen one intact...And I own it,I can supply you a picture if you like.they did make a few of these in a three series run,but it seems very few survived.Ive been told many times that they would over heat often,making them pretty much a failure.BUT mine runs fine,although I dont mow long grass so Ive not really tested it under load.At a guess going of the few numbers ive obtained they maybee made around 20,000 or so.Anyways I love this model and im currently restoring her now.Only missing a catcher,but i doubt id ever see one.
And the "Magister" is the "black box" some of you are refering to,its a solid state sealed coil unit that amplifies the power to the plug,simple design,but truly,In my opinon totally unecessary since there is enough room on the coil plate to run 2 victa coils.Anyways hope this answers some questions...And YES you wil be able to get an alternative of another mower to run this im very sure.
Please dismiss my previous entry on another of Blumblys posts relating to this matter smile
