[QUOTE="onthewater102, post: 463511, member: 13702"] I believe they called that an enrichment valve. It's a side reservoir under pressure from the fuel bulb that when you press down on the blue plunger allows a shot of extra fuel to flow through bypass channels in the carb. In the cold especially you do not want to leave it pulled out when you go to start the motor or you will flood it as fuel will keep flowing through the bypass with the valve open. Prime the bulb in the fuel line till it's hard, then pull the knob out for the enrichment, you'll hear a squirt of fuel go to the carb. Push it back in, prime the fuel line bulb again and pull the knob out again for another shot - then push it back in and try to start the motor. [/QUOTE]
