Just had a young man of about 17 come by the house that lives in the neighborhood and likes to fish. That in itself is pretty amazing these days. Said he and his Dad just tuned up their 1970 Evinrude 4hp and it was not running correctly. Told him to drop it by the house and I will look at it.
Long story short - All Sierra components in it plus aftermarket plug wire.
Points did not line up
One new condenser dead already
Coil air gap different between the two coils at the center post.
Weak spark out of both coils.
Screw this! I replaced the entire ignition system with good used parts I had in stock plus new OMC condensers.
Replaced the ignition wire as well with OEM Belden cable and new coiled plug end terminals and boots.
New properly fitting boots at the coil high tension outlets.
My good used coils put out a hot blue spark at a 3/8" gap consistently with correct OEM components supporting them.
Engine ran like a watch and all that remained was to set the low speed mixture.
Showed him a short video of his engine running today. He was happy.
Got to help out a kid that loves to fish!!
