Re: Revenge C.R. Style
Probably a thin disc of material left over by a hole punch put over contact to a plug wire on the distributor cap. Eventually the high coil discharge voltage would burn though and the plug would fire on a cylinder flooded with gas causing the backfire

Like a bursting disc on a twin cyl. NH3 compressor?
Not this time.
Chippy/ Shipwrights wear this necessary bit of kit normally behind the ear?
H.T.. area here applies.
BP's ideas on track.

Oh placing graphite from the pencil between the contacts inside distributor cap providing a conductor between the contacts and causing multiple plugs to spark at the same time which will almost guarantee a back fire.

Re: Revenge C.R. Style
Nearly there Dave,
So it's off with the plug cap, out with the pencil and draw a thin carbon line from top to bottom of the ceramic insulator.
As we all know HT current will always take the easiest route so instead of tracking down the centre electrode and hurling itself across the correctly set gap it runs straight to earth thereby bypassing a spark situation.
Then stand back and watch the victim remove and strip the carb. etc etc.
Used to have a lot of fun doing stunts like this particularly in the old days especially when you had a BC ( bus conductor ) lookalike.
Sometimes hours of fun to be had again at someone else's expense.
Works on multi cyl. outboards too.
And old V 8's.
