So, maybe to you Midwesterners this is no big deal, but out here in California, normally, I make a practice of starting my engine (2003 Yami 225F) at least once every 1-2 weeks...regardless of whether or not I'm going out to fish. Well, we've had some major closures on the west coast recently and therefore there has been virtually nothing to fish for. Anyway, my engine sat cold for 5 months and I was afraid something was going to go wrong on start-up. Well, I put in a little Yamaha Ring Free in the gas, turned the key, and three seconds laterresto! She ran beautifully...no smoke...peed like a race horse...idled smooth as a babies butt ran solid and just as strong as normal at cruising speed. Guess modern day four strokes are pretty darn bullet proof.
