How is it built like no other 2 strk? All they did was take the idle circuit out of the carb, Hardly groundbreaking. More than likely an attempt at lowering emissions and improving idle quality.
Make sure you test drive it. All the 4 cylinder mercury 2+2 topped out at 5250 rpms and not all had tev limiter. Trying to rev one of those to 6000 Rpm is a good way for inside bits to become outside bits.
It's a carbed motor, perfectly normal to have to give it throttle after 5-15 minutes of sitting. If you don't want to give it throttle buy an EFI motor.
