RE: [oletrucks] (NON-TRUCK QUESTION).. .How ignition works?

["Hanlon, Bill (ISS Houston)" <bill.hanlon@hp.com>]

Your "one spark per revolution per cylinder" may be true of late model
engines that get their timing info from a crankshaft based mag pickup,
but most 4 cycle engines with distributors fire "one spark per every
two revolutions per cylinder".

oletrucks is devoted to Chevy and GM trucks built between 1941 and 1959
