I finally got around to doing the De-carbon process a few weeks ago. I mixed 16 0z of seafoam with 3/4 gal of gas/oil mix and sprayed aerosol Seafoam into the plug holes. I ran the motor on the mix for about 20 minutes, then let it sit for about 20 minutes and then repeated for a total fo three times. Each time, my barrel had a oil slick of black foamy crud. Less each time though. 

 The motor definately ran better. Idled better and warmed up faster with less smoke. After running it 4 or 5 times though the smoke seems to be increasing slightly. I added another can of seafoam to about 10 gallons of mix in the tank but havent ran it much since.
