Viking 16hp - Briggs Has No Spark
Posted July 12, 2012 - 11:15 PM
Tonight I finally got around to cleaning up the carb and now there's no spark.
It's a 1972, 16HP briggs with magneto ignition and external points.
Tried a few different plugs.
Removed the kill wire.
Any high probability suggestions? I find it odd that the coil may have failed.
I'm looking at the number of pieces that have to come off to get at the magneto and I don't have a spare one to try.
Is there any way to test the coil? High tension winding resistance?

Try re-setting the points and taking some fine sand paper through the points[ be careful the points are only held in place by a tab and spring tension, and pop out if you look at them crooked ] then run a clean piece of paper money through to clean points.
Sometimes they can be contemptable in high humidity.

These engines do not produce the greatest spark at lower RPMs, so you may never see a visible spark. I had two engines like this with no visible spark, but they both started and ran.

The cheaper,easier fix would be to replace the condenser and Clean and re-gap the points.
Condensers are around $12 and an electronic ignition coil is around $45 off of Ebay.
