Re: CD17 5.5Hp Compression question

If it runs, the best way to unstick the rings is with OMC Engine Tuner, or seafaom.

Both work very well.

I mix a heavy dose with the pre mixed fuel, about a gallons worth.

Then I put the rest in a spray bottle. Run the motor at a fast idle, and pump the seafoam into the carb throat. She will smoke like its on fire! Empty the solution into the carb, then let it die. Let it sit overnight, to break up the carbon. Then in morning, take for high speed run. May need to change plugs after. I have increased compression dramatically this way, if the rings are stuck. Its not magic though, wont fix damaged piston, damaged cylinder, etc…
