I just acquired a 5HP Sears Tecumseh/Eska with the magneto ignition (it's a 1970 model
Spark initially was weak sometimes/non existent other times. I replaced the condensor. The points looked new...but I cleaned then a bit. The coil certainly looks OK.....but I need to check that now somehow.
Do coils typically fail? I've never had to replace a coil yet.....I initially doubted that the coil would be bad.....but I guess I might have been wrong.
Can someone walk me through the procedure to test the coil?
you should be able to get a 1/4 in spark in air if its going to be any good at full cylinder pressure but you may not get that ..the colour and look of the spark is not relavent ..if it jumps the gap its good ...as output is low at low rpm you may have to pull the gap down to 15-20 thou on the plug
