84 90

[ddzeke]

I have a 1984 90hp Johnson, It starts on the first crank almost every time, let warm up and will run for hours, but if I shut it off it won't restart for 30mins to and hour, cranks and cranks but know fire. then for no reason it will just start and run like it's brand knew again. Are there any ideas on what this might be, this just started out of the blue.

Check compression. Check for for spark at plugs when fails to start.
