Compression test

[Joker2]

I have been adding the Sta-bil for ethanol every time I get gas since I got the motor ( last Sep. ) when it was newly rebuilt. I am thinking more about a product for decarboning. I just got a known good compression tester yesterday, I will do that first and see what my results are. I only have about 18 hours on motor, ( 10 hrs of break-in running double oil ) it seems like not enough to have to decarb. I have a 20 minute ride at idling speed each way till I get to open water every time I go out, wondering about how that is for buildup ? trying to get it to run smoother at idle and get more power out of it, only 45-4900 RPM's max 25 MPH on GPS
