been running good for a year, its time to decarb, no reason to wait for symptoms

I decarb every new customers engine when I first service them. After a good heavy decarb, they only need a annual decarb on average. I also recommend running Yamaha ring free or mercury carbon guard in every tank(reduce the ratio, Anytime I pull plugs on an engine, it gets a heavy shot of mercury power tune. Optimax owners I tell to run a portable small fuel tank with a heavy decarb mix in it to their engine and run them at least 20 minutes on it, let it sit for a couple hours, then switch back over to their regular fuel. Do this every season or 100 hours
