What are you working on? 49cc 4 stroke? How many miles? What size and brand carb? What size is the main jet? Was it running before the changes? How long ago? How does it run once started? ?? Covering a portion of the back of the carb richens the air-fuel mixture. Your not getting enough fuel. If you suck on the vac line for the petcock does the fuel flow freely? Oh, and Welcome! Thank you for your service.
