Hi, im new to this form. Im struggling to find a manual to set my carberator float level. All the carberator that i find dont match mine. Mine only have one float on the dublle carberator, not like the others that have 2 floats. I have cleaned the carbs because boat was riding rough, and now the motor does noet want to start, new plugs, new fuel filters, disconnected the fuel pump and it does pump, primer bulb gets hard when pumping, new fuel mixed 50:1. If i spray quick start the motor start but dies after a second. Spark is also good on all the plugs. So i think this n as fueling issue. I finded on the carberator that the jet that sits in die middle of the carb bowl was completely loose.
