Need some help. We are working on a Yamaha 50 2 stroke. I hate just throwing parts and something but at first it had irregular fire so we replaced the CDI. Then we still had irregular fire so we replaced the lightning coil. We have rebuilt the carbs, reset the floats, and went completely through the fuel system (including replacing the fuel pump) from the tank through the engine and motor has good fire, fuel is getting through the carbs but it just will not start. The carbs have been sink and linked. We can spray carb cleaner in to carbs and it acts like it wants to hit but it wont. Help please !!! Thanks
