Sea Foam and Compression Results

[roger3645]

1975 Merc 850, has good compression in all cylinders except #3 which was at 90 PSI. After 2 sea foam treatments #3 is now a bit over 100 PSI and other 3 remained about the same. Should I give it another sea foam treatment? I have not had it in the water since treating the motor with sea foam. I've also removed and cleaned the carbs and she idles very smooth now. Can the compression on #3 continue to increase after a good run on the lake. I'm hoping I've freed up my rings that were stuck due to carbon build up. Thanks!

Add SeaFoam to each tank of fuel. It will provide continued de-carb although at a slower rate than doing it in concentrated form. Wouldn't hurt to give it another shot though.
