Hi, no this motor has been in use, but probably only has 50-100 hours on it since 2009. I put up with the miss, because the guys who rebuilt the motor were in the process of closing their business, and arent efficient at getting services done. Highly reputable place that was in business since the 1920s, knew these motors inside and out. You might be surprised but outside of the paint, this is a pristine motor, dollars spent well beyond its worth to bring it back to reliable use in 2009 - full rebuild including pistons, rings, (1970s flat tops and rods), newer carbs, power pac, coil. Gearcase was resealed a few years earlier, impeller changed in 2009 and I will change it as soon as replacement arrives. I replaced engine wire harness several years before that but still in nice shape.
It ran really poorly in 2010, and I did bring it back to the shop and they found a defective coil, but the miss continued.
