heres the situation. I'm getting a very intermittent spark on all cylinders. the powerpacks, timer base and stator have all been recently replaced. i checked the rectifier and it tested good. the mechanic at my marina hooked up a test start box to rule out the kill switch and ignition switch. when i do get spark it is a good blue spark and will jump the 7/16 gap. my engine is a 1978 evinrude 140 model 843c

Re: evinrude 140 intermittent spark

did you have the same intermittent spark before changing all the components?
