Gas is spitting out of the top carb on my 74 50hp Johnson. If I spray sea foam in the bottom carb, it wants to die out but no affect when doing the same to the top carb. Possible Reed valve problems? Great compression on both cylinders,,,,,,,,,
Hi all, I'm new here as well as new to the world of working on outboards. I've done a lot of automotive and truck repairs over the years but this is my first outboard engine. My 1974 50hp Johnson will not idle and seems to have a miss also. I've rebuilt both of the carbs and put new spark plugs...
