    Does spark jump a gap of 1/4" ( 8 mm ) or more, yes or no ?---Or just not sure why that test should be done ?

    Typical symptom of bad coils, but that is jumping to conclusions.

    I'll check the gap and spark.

    Could that be because the coils get to warm, just wondering?

    Old OMC coils are notorious for age-cracking, that's why we automatically assume. Besides, we don't know whether yours are original or replaced last week. And also why racer said check the spark. BTW, old cracked coils can throw a weak spark, but not run. But nevertheless, a spark check is the first place to go.
