I have a 1974 70hp Evinrude model #70473M. I had it out twice this year. First time out it ran fine except for a brief second where it (burped) lost power then recovered. Second time out it was running fine then started to burp and then quit running completely. Couldnt even get it started after that.
Getting blue spark on all 3
Fuel from tank, bulb, quick disconnect good
Gas was stored with Sta-bil over the winter
Fuel filter clean
New impeller last year
Carbs rebuilt last year
What's the right way to check compression and fuel pump if that's what is causing this? Any help is greatly appreciated.......the fish aren't gonna catch themselves
