I have a 1971 Johnson 85 hp that I am having trouble getting started. I have read many treads and the service manual to help trouble shoot. Motor will run for short time (30 seconds) then shut down and backfires through exhaust. Seems like timing issue?? My main question is when I test the Amplifier it shows as being no good (tested by using test light on pin 5, blue wire to coil and cranking over). But I still have good spark to my plugs. I wanted to get another opinion before I spend a couple hundred on the new amplifier. I did just read and old tread on how to test the amplifier using a different method. Will try when I get home. Anyway thanks in advance, Cory.
